Ford Ranger / B-Series :: 1987 - Rough Rolling Idle / Stall Out And A Lot Of White Smoke Out Of Tail Pipe
I have a 87 ranger with a 2.9 and recently it started to act up when i start after its been sitting for a couple hours it has a rough rolling idle and will stall out and a lot of white smoke out the tail pipe and some times a tiny bit of black smoke when revved high....after a about 10 mins of feathering the gas it will even out and runs no problem.... oh and quite a bit of moister comes the tail pipe....and this issue just occurred over night every time before never had an issue like this...

I have a 2002 ford ranger xlt 3.0 i just rebuilt the entire motor about a month ago and was having a high idle problem for the longest time. turns out i had the iac on backwards. but now that it idles down around where its supposed to it has a rough idle has a little shake to it. starts up right away but when i drive down the road around 3000-3500 rpms its missing on cylinder #3 from what the code I am getting "multiple cylinder misfire, #3 cylinder misfire" I've replaced plugs and wires. camshaft pos sensor. I am getting 65 lbs of fuel pressure. spark on all cylinders. I am really at a dead end here. Also every time I take the plugs out to look at them they look brand new.

Compression seems fine,but where do i go from here? Anything else i can check/replace to solve this?
Ford Ranger / B-Series :: 2002 - Rough Idle Codes / Cylinder 2 And 3 Misfiring
I have an 02 ranger xlt 3.0, it started having a rough idle, codes say cylinder #2&3 misfiring, changed plugs, wires, coil pack, didn't work, still same code, checked injectors on right side, all 3 had ohm reading of 15.8-16.5, the injectors were clicking like they are supposed to, sprayed carb cleaner around the intake ports, didn't change the idle at all,what else can I check or do? with out tearing the engine apart, unless of course I have to, the truck has been very good to me, it's got 205,000 miles on it, I need it to last at least another year...
View 4 RepliesFord Ranger / B-Series :: 2004 - Rough Idle - CEL With P0303 And P0316 Codes?
I love my Ranger. I'm quite impressed with the power and durability. I'm ticked at Ford for stopping production.
I have searched my problem and could not quite narrow it down. I have also tried several remedies with no improvement. I need to narrow it down to a specific item.
2004 Ranger, 4.0 liter, 4x4, 131,000 miles, runs great above idle.
Problem: rough idle, idles at about 750 rpm's. If i raise the rpm's to 850 and up, smooth as silk.
The truck did this a few years back. Not quite as rough and it went away by itself.
Engine light came on this time with P0303 & P0316 codes. I have replaced: plugs, wires, coil pack. I know that the #3 plug is sparking quite well. the #3 injector is getting signal to spray not sure if it is. I have 4 O2 sensors and I believe I tested them correctly (passed). The passenger side upstream or pre cat sensor has not been tested yet. Had to rent a tool and will do that in morning. I slid a piece of aluminum roof flashing between the crank position sensor and the crank pulley. Not a noticeable difference. While at idle (750 rpm's) I pulled each (#3,2,1,) (one at a time) injector wire plugs off the injectors. No noticeable difference. I pulled the vacuum line off the egg and operated it with a vacuum tool. Seems to be working fine. Sprayed carb cleaner around on vac lines. No engine surge
Ford Ranger / B-Series :: 2002 - Cylinder 2 Misfire Code / Idle Rough When Warms Up
I bought this from my brother in better than mint condition. Always maintained. Its generating a cyl #2 misfire code.
It starts and runs like new when cold, but when it warms up, it idles rough, and generates the code. after 1500 rpm it smooths right out and runs fine.
He had it to the dealer just before I bought it and they told him needed a new engine.
I am thinking bad injector, since what seems to be happening is, when cold it gets more fuel, or when u rev it gets more fuel, but at an idle and warm, it doesn't seem to be getting enough maybe. And I see from the maintenance records, a couple of other injectors have been replaced as well.
I think the dealer got tired of replacing injectors under warranty and tried to milk him for a new engine.

Ford Super Duty (1999-2016) :: 1997 F250 Started Blowing Steam Out Of Tail Pipe
I was driving my 97 F250 2wd the other day and it started blowing steam out the tail pipe. In recent months I have replaced the thermostat, heater core, and pressure cap on the reserve tank. I do believe I have blown a head gasket. I did check my oil fill cap and it showed signs of milky residue..
The motor in trouble here is the 4.6L gas. And I have yet to talk with my mechanic I had the thought to replace this one as it has over 330K kilometres on it. I wonder if a newer 4.6 from a similar F150 or F250 would have the same motor mounts. No, I am not looking at brand new as my budget isn't that of a millionaire. I have found a few younger 4.6 motors within my budget.

View 3 RepliesFord Ranger / B-Series :: 1999 - Intermittent Misfire On Startup - No Codes
Previously on "This Old Truck": [URL] ....
Mileage now 298,5xx. Done since last report: Oil change and filter. Trans oil change (merconIII, no leaks apparent). Tires. Front brake pads. Clutch safety switch (was interfering with cruise control operation) Coolant replacement. (see below)
Rat damage related overheat (near total coolant loss, but no MIL) at 288k. (Rat suffered acute lead poisoning later that night) No sign of rodents since.
Fuel filter change (after onset of symptoms).
NO MIL/CEL, no pending codes. CEL/MIL operates on KOST.
Temps normal (190F +/-2 deg during steady-state cruise operation, fuel flows and fuel mileage have not changed significantly. (fuel mileage has IMPROVED approx 5%, possibly due to gentler/slower driving)
M5OD with Limited slip 3.73/ payload pkg II (1650lbs)
Symptoms:
- Intermittent misfire on startup, seems to get better as the truck warms up. (intermittent= some days it do, some days it don't.)
- Truck starts and idles well, even with misfire.
- Intermittent loss of power, usually worse on days when no- or minor- misfire at startup/cold idle. From the driver seat it feels like accelerating over painted lines on a rainy day. . . a couple revs of no power, then it pulls hard for a second or two, then misses a couple of shots, lather, rinse, repeat.
- Usually worse in higher gears; (not noticeable in first or 2nd, bad in 3rd at high power settings, now almost constant in 5th, to the point that truck will not accelerate below 3000rpm in 5th even on flat ground.)
- Fuel flows above 4GPH/ OBDII "LOD" (engine load) reported above 75% are typical during malfunction. (Fuel flows have been as high as 9GPH with no problems on other days.)
Symptoms started at approx 292k and have been slowly getting worse over the past few months. . . . usually worse at beginning of trip, fading to very occasional after 50 miles of high-speed driving. Some days/trips no noticeable malfunction.
Thoughts:
1) Ignition wires tired? (did visual inspection, no obvious damage, but no water spray test performed, but seems likely given that the problem is most evident in conditions that would lead to high cylinder pressures.)
2) Fuel pressure? (not measured yet. . . original pump but possibility discounted due to intermittent nature of malfunction.)
3) O2 sensors tired/rat damage? (Original units still installed/ no obvious damage on cursory visual inspection under truck)
4) Injector going bad or injector wiring rat damage?
5) Plugged catalytic converters? (no sound of blown exhaust gaskets, exhaust flows well at tailpipe, with puffs at misfire.)
6) Cam sensor? (never been replaced; known issue with this model engine. Had intermittent mystery squeak that came and went at approx 250k-260k)
7) Clutch slipping? (never had one do that; always lose the throw-out first)
8) LSD problem? (fluid level/ appearance ok, last changed 150k; would expect worse in LOW gears)
9) Blown head gasket/s?
10) Cracked heads/ block? (Oil and coolant levels and appearance normal)
So: That's the plan of attack. What am I missing? (Clutch last done approx 170k; burned throw-out, did disk, flywheel, pressure plate, slave cylinder while the trans was down. I did not open the hydraulics or disturb the pedal linkage when I replaced the safety switch. )
Ford Ranger / B-Series :: 1998 - Codes For Lean Bank 1 And 2 - Cylinder 4 Misfire
1998 ranger 4.0L. I ran my scanner on my truck to day and my 2 bank 1 sensors seem to be bouncing between .150 and .700 but my bank 1 sensor 2 seems to be stuck at 680-720 and not bouncing, is this normal?
I did pull a code po135 heater circuit malfunction BANK 1 SENSOR 1 ...
Also I am not sure where my fuel trims should be...
My
ST1 10.0
LT1 25.0
ST2 12.0
LT2 25.0
closed loop.
When I first got the truck I pulled codes for lean bank 1 and 2 also a cylinder #4 misfire and the bank 1 sensor 1 heater circuit. I reset the codes and the heater circuit bank 1 sensor 1 popped the mil light in 5 min. So I am starting with the o2 sensors. I've not found any vacuum leaks at this point.
Ford Ranger / B-Series :: 1986 - Starts And Runs Rough / Bad Misfire
My pops has a 86 ranger with a 2.9. And what its been doing is, it will start up just fine then u give it a minute and itll start to run very rough like a bad miss fire, then if he revs it up for a bit. It will clear out and then run just fine until he starts it up again and it seems to do it more the colder it gets and it smells very rich. Iv checked the injectors and there fine, what other things could it be ? O2 sensors oorrr

2003 Ranger FX4 Flareside
4.0
Automatic
145,000 Miles
Here's my issue: My Ranger has been running like a dream until yesterday.
I took off on a parts run for my sons Ranger. I got to a stop sign and as I stopped, it started missing and barely running. I nursed it back home and checked the flashing CEL. It was giving me a misfire on #3.
Since I had been planning on changing the plugs and wires, I dove in and got it done hoping that was the cause of the misfire.
Started it up, same thing. I went to the next obvious item: coil. Replace it, still running like crap. Gave up for the night.
Today, I thought I would dig in using the tips here on the forum. Did the spray down...no errant spark anywhere. Tested fuel pressure: 65psi no drop in pressure on acceleration.
Started pulling wires off the coil one by one. Four of the wires resulted in running worse. 2 had no effect. #3 and #6. The coil was producing plenty of spark on all 6 ports.
At this point I was sure it had to be 2 bad injectors. Since I couldn't get injectors tonight, I moved them around after cleaning them a bit and tried my wire test again. The problem stayed on the back 2 cylinders!?!
I tested for voltage on the back injector plugs and I am getting voltage. I also used a stethoscope to listen to all of the injectors. The back 2 seem to remain silent. I have also unhooked the battery for 20 minutes to reset the PCM. Still missing and running rough....
Here's a list of what I have done:
Autolite Double Platinum APP5144 plugs. .062 gap
Autolite Pro Series wires #97051
BDW E97P Coil
New air filter
What should I do next? I really don't know where to go next.......
Ford Ranger / B-Series :: 2002 - Occasional Misfire At Idle Only?
Misfire is on #6. Feels like a partial miss, not every revolution, and there's no noticeable miss while cruising or holding a higher rpm in neutral. It's a B3000 with 97k miles. New Motorcraft plugs, new wires, 10.7k ohms across coil terminals (1-5, 2-6, 3-4).
I've swapped plug wires between cylinders and side-to-side on the coil. I also sprayed MAF cleaner all around the intake looking for a leaky gasket. I feel pretty confident I'm looking at a bad/dirty injector or valve issue. I plan on doing a compression test next and hopefully nail it down to one or the other.
I'm asking for input on my diagnosis so far. And how difficult is it to replace the injector? Will I need to remove the upper intake?
Ford Ranger / B-Series :: 2003 - Misfire Only At Idle Always On Cylinder 3
I have a 2003 Ranger edge 3.0 flex fuel 183,000 miles. I have been having a misfire problem, only at idle, always cylinder 3. Replaced the fuel filter. Just replaced fuel pump assembly. With the old pump my fuel pressure was 49psi key on engine off, and running at idle it was 59psi with a shaky needle. With the new pump, when I turn the key on it jumps to 60psi then imedietly drops to 49psi, when the pump shuts off. Running it is at 60psi with steady needle. Koeo the pressure holds good at 49psi but does slowy decrease, about 5psi in 15 minutes. What would be causing the pressure to drop to 49psi? I am checking pressure at the fuel rail. Pressure according to the haynes manual should be 60-65psi koeo and the same while running at idle.
View 14 RepliesFord F-150 (2004-2008) :: Rough Idle / P0012 - Misfire Codes Associated With Bank 1 And Cylinder 3
5.4 3v. my last few weeks have not made me a fan. Here are the details:
I bought a 2008 F150 XL 5.4 3v with a cam phaser knock. Have done other timing jobs in past with no trouble so I was not too afraid to tackle this one. famous last words...opened the motor (shout out to the passenger side valve cover and its designer here) and found semi damaged roller follower on driver side. Worn cam lobe on the corresponding lobe and a loose chain on passenger side. proceeded to :
Change all timing components: phasers, chains, tensioners crank sprocket, all applicable bolts and BOTH cams as well as all lash adjusters and roller followers. most looked fine in fact all really did with a bit of wear on a few roller followers but only one bad one. engine didn't look to bad pretty clean.
Double and triple checked my timing chains and it was spot on. dark link on spot on crank, two dark links on the L and R dead on. put it back together. oh yes, changed all plugs with motorcraft ones, didn't even break one. did not change vct solenoids because I falsely assumed I could change the later easily if needed. they looked ok. screens intact etc... silly me for not realizing how kind Ford was in 2007 and later to necessitate removal of valve cover. I was reading a previous one on the how tos and assumed later models would be the same since it was the same sensor...
Cranked truck ran great. I mean perfect. sounded perfect. ran like a scalded cat. till it got to hot idle then it started doing its thing. rattle shake till you revved it. ran fine just wouldn't hot idle fine especially in reverse or under slight load. replaced driver side vct since ford only had one and I started on the easy side ordered the other one waiting for it. seemed to improve dramatically meanwhile I am driving this truck to test it. I drove it to work 50 miles each way and it ran great.
After a few trips it popped the P0420 light, seemed to run ok, cleared it watched it wouldn't come back. O2 sensor did seem to imply a bad cat on bank 1 since it seemed sensor two was mimicking sensor one and not staying stead like the other bank. still ran fine,
So I decided to check back pressure on the cat. I pulled sensor one out of bank one (really a joyously tight squeeze in there) hooked up my gauge and got 0 back pressure. revved it and all nothing. hooked sensor back up pulled truck out of shop and it commenced to running like crap. I mean bad. running worse than before I got it. Popping P0012 code continuously, and tons of misfire codes associated with bank 1 ..cyl 3 etc.. I tried swapping coils, pulled coils and checked spark with a tester and firing away looks like tons of good spark.
Now the weird part is : looks like bank one is dead. I can unhook any coil pack and/or injector and it runs the same and sounds like it is missing. if I unhook one off of bank 2 it almost dies or does. so bank 2 seems to be running fine. it will start and run but sounds like it missing sets flashing check engine light and backfires and stalls like crazy. I even second guessed my pressure gauge and unhooked exhaust manifold from pipe and it sounds even prettier when it backfires out of there but no change. I pulled cam sensors and cleaned it again and even tried swapping them since they looked identical but no change so I put them back.
Now I can only surmise that I am out of time somehow? or I have a gremlin perhaps? I like working on cars (usually) but this one is getting old. how do I verify what is wrong. if it is timing related how do I verify that now definitively once my marks moved I really cant figure out how to tell if it is in time? Since it has all new parts and they all ran beautifully till now. could it possibly be the vct solenoid doing all this? I plan on changing it when it comes in but surely it cant cause this many problems.. I unhooked it no change, and it does it at a cold idle and any rpm. really runs worse at idle but bad at any rpm.
Ford Ranger / B-Series :: Misfire Code / Engine Vibrating Bad At Idle (hot)
I have a 3.0 Ranger, AT 2WD, from 2001 with 175K miles on it. I have a CEL on, with Misfire cylinder #5.
Also when the truck is cold and I step on the gas, it seems to run on like 3 cylinder for 2-3seconds and then it somehow fixes itself and runs great until it warms up.
After it warms up, it shakes violently at idle. The shaking goes completely away once I'm past 1200 rpm or while driving. What I tried so far:
- All new Motorcraft filters (Air, fuel)
- Motorcraft Plugs
- Motorcraft Wires
- Motorcraft Coil
- Ran thru two cans of SeaFoam
- Checked injector resistance
- "Reset" the ECU
- Cleaned MAF sensor
- Cleaned IAC
What else I need to check?
Ford Ranger / B-Series :: 2006 3.0L - Intermittent Low Compression And Misfire At Idle
I bought a used Ranger a couple months ago and it ran fine when I test drove it but a week later it started having a misfire every now and then at idle.. I must have gotten pretty unlucky with the test drives..
The misfire comes and goes, it will run fine for a week or two and then it will misfire at idle for a week or two. It only seems to misfire at idle, the truck runs rough/shakes but once you give it a little gas and start moving it goes away. Usually it has a check engine light on from startup when it's misfiring and it goes away on days that it's running fine; it will occasionally misfire at idle with no check engine light. Sometimes when its running really rough the CEL flashes while it's misfiring at idle and I've actually restarted it real quick and the misfire went away for a bit. The engine codes that come up are misfire on startup and misfire on cylinder 4.
I've tried cleaning the MAF sensor, replacing the fuel filter, testing for spark and compression. Compression was 150-155 PSI on all cylinders, however, the compression on cylinder 4 is different depending on whether the truck is running well or not. When it's misfiring the compression on cyl. 4 is 90 PSI and when it's running fine it's 150 PSI. I'm not sure what could be causing intermittent low compression like that?
Camry :: 2.4 Engine - Misfire Codes And Rough Idle
The engine on my camry 2007 was overheated and I had the headgasket replaced but now it has misfire codes and rough idle this is a 2.4 engine I replaced 2 of the coils but still it has a rough idle... when the car is running it runs pretty good.
