Ford Ranger / B-Series :: 2002 XLT - Rough Idle - Misfire On Cylinder 3
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.

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 Ranger / B-Series :: 2002 - Running Rough Like Misfiring
My ranger just started running very rough. Like misfiring, but I think it may be the fuel pump. It starts and drives...but it surges then drives normal, as if fuel is being fed, then starved, then force fed etc. My father asked if I had trouble starting it and to be honest in the last 6 months it was a little harder to start on several occasions. On a few occasions it required more cranking. But that was only a few times.
I tried putting in a fuel injector cleaner and 93 octane gas but it is still running even rougher now. I changed out the fuel filter under the rail about a year ago (maybe 8000 miles ago at most). My father thinks the fuel pump is shot and he laughed because his went on his expedition and he said it is inside the fuel tank and there is no way to get at it without dropping the tank. Is that true? 2002 ranger xl 4cyl
Ford Ranger / B-Series :: 2001 - Rough At Idle / Misfire In Cylinder 1
So I have a 2001 ranger 2.3l . Runs very rough at idle.code says misfire in cyl.#1. I have changed plugs, wires, coil packs all motocraft. I did a compression test..
#1.170
#2 180
#3. 185
#4 . 180
Compression seems fine,but where do i go from here? Anything else i can check/replace to solve this?
Ford 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

View 3 RepliesFord Ranger / B-Series :: 1998 - Which Cylinder Misfiring
I got this 98 Ranger 2.5 that I've done a tune-up on less than 30,000 miles ago. I changed plugs, wires, and both coil packs. Timing belt, thermostat, fuel pump, fuel injectors are all recently changed too within a year or two. Fuel filter and air filter I change every 30,000 miles. The truck runs as great as a 4 Cylinder will run. It's at 344,000 miles but the engine was changed once so it probably has over 100,000 miles on it. There is just a slight miss you can hear through the tailpipe but it's not severe enough to be picked up by the Check Engine Light. In fact, even when the coils were totally gone it never put up the Check Engine Light. I can tell when a coil pack is going out on this because it's done it several times so I usually just change them with the tune-up. It's only a slight miss some people may not even notice it. I was just wondering is there any way to track down where the miss is? I tried looking under the hood in the pitch black and there's no plug arcing.

Had a misfire in cylinder 1 so I put new plugs and wires. Still misfired. Changed fuel injector. Still misfired. Changed ignition coil and misfire on cylinder 1 is gone now cylinder 2 and 3 are misfiring. I double checked wires and they are properly installed.

My 2003 ford ranger 3.0 v6 is having a misfire on start up and it is located in the forth cylinder. Where to start to get rid of this problem. i have already changed all my plugs wires and even the coil pack cleaned out the maf and looked for possible leaks. the car shakes really bad at lights and the check engine light starts to flash. Need diagram of where all the cylinder numbers are at and maybe the firing order?
View 14 RepliesFord Ranger / B-Series :: 1987 - Misfiring - Run Rough - Loss Of Power - Dying
My brother's 87 ford ranger 2.3L truck began to have problems. It would be running great, then start to misfire, run rough, sputter, shake and loose accelleration then die. Then it wouldn't start back up for a long time, sometimes til the next day. Little by little, the truck would drive a shorter and shorter distance between breakdowns. He first tried some minor work himself, (basic tune up) - replaced his rotor, cap, plugs, air filter, fuel filter, but that didn't fix it. He went to one garage (big mistake), who said the fuel pump pressure was fine but said he found a broken wire on the harness grounding out and it needed new ignition module and replaced it. (Cost was $350.00+), Garage promised to honor any additional work nec if it continued to have the same problem, and would be free of charge.
Five more breakdowns later and two more "better quality ignition modules", new battery terminals, and 1 new computer later, this joker did more unauthorized work and demanded another $200+ besides the fact of breaking his orig agreement "free of charge" if any further problems! Needless to say, second garage fixed the truck by replacing the magnetic pickup, part # DU 30-C (an electrical part that goes in the distributor and pulsates a current to operate the timing) (it does something like that) and the truck has been driven approximately 40-60 miles as of today, (3 days later), without breaking down. All the other times when picked up from incompetent garage, it wouldn't go more than 1 - 7 miles before breaking down and each time they didn't fix it.
Ford Ranger / B-Series :: Misfire Codes Started Out On Cylinder 5
I am currently chasing misfire codes that started out on cylinder 5 p0305 was the first code I replaced spark plugs and wires about 200 miles the code returned checked coil with meter it was barley in spec. I have replaced coil same code only difference was a hard start cold or hot replaced injectors now hard start is fixed but logging codes for right bank is to rich and p0300 304 305 and 306 also performed compression test on right bank and readings are 155 155 and 160...
View 3 RepliesFord F-150 (2004-2008) :: Misfiring - Rough Idle - Got Codes P0340 / P0344 / P0345 And P0349?
I recently purchased a Ford pickup. I bought a 2004 F-150 with the 5.4L 3V engine. I have only driven it for about 300 miles so far and am having problems. The engine has 200,000 miles on it. I have read several posts on here about the cam phasers which I believe that I may have some issues with. The engine will run good when cold, on the road, etc. The engine does have a slight ticking after it warms up (cam phasers?). When I come to a stop after the engine is operating temperature, the engine will start to miss and shudder and all 4 above codes come active and are also pending (8 codes in total).
All 4 codes are logged at the same time. I have replaced both cam position sensors, both sensor ends and terminals for cam position sensors, checked wiring around rear of engine (does not appear to be rubbed through), all plugs were replaced, and all COP boots are good. Is there anything that can cause these codes that may not be the actual cam position sensors, ie. VTC, COPs, cam phasers? What pins the cam position sensors come to on the ECU (so I can ohm the entire wire harness)?
Also, if the engine is missing with the codes active and I rev the engine up it will come back to idle and run great. The engine never dies out, just runs horribly. I have also unplugged each sensor with the engine running which has no effect on the way it runs.
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

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 - Taurus :: 2002 - Rough Idle / Misfiring During Operation?
I just recently purchased a used taurus and was experiencing rough idling and misfiring during operation. I replaced the EGR valve, the egr sensor, coil pack, spark plugs, iac valve, as well as check for vacuum leaks near all the hoses. I am a novice when it comes to this, but I was able to change those without issue. The misfiring was fixed during driving, but I still have rough idling. The needle seems to stay in check pretty well and the check engine light isn't on, but the car kinda hesitates and it causes the car to rock when idling. You can also feel the stuttering and rocking when cruising at very low speeds (5-15mph). I've already plugged in a decent amount of money into parts and am running out of patience when it comes to fixing what is a "potential" problem, and it winds up not fixing much.
View 5 RepliesFord F-150 - 1997-2003 :: 2002 V6 Misfiring - Rough Idle
I recently picked up a 2wd 2002 F-150 with a 4.2l V6 that has just over 300k miles. The CEL is on and I'm getting P1131, P1151, P0316, P0305 and an occasional P0301. It has a very distinct misfire from around 1,000 rpm and smooths out between 1,500 & 2,000 rpm, the idle rpm occasionally bounces (sometimes enough to stall), and the idle is sometimes rough.
I have replaced the plugs, wires, fuelfilter, and replaced a leaking PCV hose. As I have changed things the symptoms have improved some but they are still there. While capturing some livedata it kept going out of CL and into OL Fault. When it would the idle quality was crap and the miss was much more significant. I would have to put it into D hold the brake and run the RPM's up to just over 1k to get it back into CL.
After I got done with the data stream at idle, I set the parking brake held the foot brake and put the truck in D then ran the rpm's up to around 1,200 & held it there. The truck stayed in CL but it would cycle between misfiring for 5 - 10 seconds then clear up and run smooth for 20 ' 30 seconds, every time it cycled there was an audible click that could be heard. Also, the AC was off the whole time.

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.
