Ford Ranger / B-Series :: 1991 - Stall Out At Idle / Back Part Of Trans Housing Leaking

1991 2.3L 5 speed .... Okay here's my list of issues.... At idle will stall out, its almost as if i shut the key off, or sometimes taking off it'll sputter and stall, fuel filter has been changed. Back part of the tranny housing leaks, is there a gasket for that?

Eclipse - Mitsubishi :: 1991 - Periodically Bucks And Surges Especially When Going Uphill

My wife has a Mitsubishi 91 Eclipse with an with a 1.8 liter engine and automatic that periodically bucks and surges, especially noticeable under load like going uphill but can occur during straight line highway driving. After doing a complete tuneup, changing the throttle position sensor, O2 sensor, having both the ecu and tcu rebuilt, check all vacuum lines, replaced ignition wires, replaced fuel pressure regulator and checking fuel pressure, replaced injectors,checking all electrical sensors and connections, etc. etc. I, nor professional mechanics, cannot determine what may be causing this condition. At this point I'm thinking either the fuel tank needs removal and cleaning or its the fuel pump, coil, ignition switch, or torque converter. Here's a clue... I'm finding an oily substance on the pavement that appears to be coming from the transmission area. It doesn't appear to be ATF nor oil. I'm suspecting the torque converter is leaking.

Ford - F150 :: Sputtering / Idle Rough With Surges

I have a 2001 f150 5.4 liter 2 wheel drive super crew that idles rough with surges in the idle. Weird thing is it only does it when it's 55 degrees or below. So it's fine now in the heat but winter is coming and the colder it is the worse the idle. Replaced maf sensor.

Ford Ranger / B-Series :: Hard To Get Out Of 2nd Gear / Engine Surges Then Starts To Lose Power

My surging/running down issue has returned on my '86 2.3l Ranger. I thought it was electrical, when things improved with the new ignition switch, but lately it's hard to get out of 2nd gear before the engine surges then starts to lose power. a poke of the gas pedal starts the who cycle over again. I pulled codes but it's hard to tell what the reader is saying either 33 and 34 or 334. The good thing is all the codes point to the EGR system. Looking for a diagnosis tree to determine if the valve is bad or the sensor is shot? They are both not cheap so I don't want to just throw parts at the problem.

Ford Ranger / B-Series :: 1990 2.9L - Bad Misfire After Doing A Tuneup / Bucks And Surges At Cruising Speed

My '90 Ranger is experiencing a pretty bad misfire after doing a tune-up. I changed the plugs (gapped to .045), wires, distibutor cap, rotor button, air filter, fuel filter, and cleaned the IAC. It had a barely noticeable miss before the tune up, that's why I did it. Now, it's pretty horrible.

At idle, it's definitely noticeable, and at cruising speeds (RPM's below 3K) it bucks and surges. The weird part about it is WOT runs are as smooth and (somewhat) powerful as ever! At idle in neutral it will revv up just fine without any hesitation as well.

First thing I did was check the firing order, again and again. Made sure all my wires were properly seated on the plugs and on the distributor prongs. Pulled the plugs back out, they were all clean and properly gapped. I pulled the wires off one by one to try to isolate the misfire, but every plug wire I removed made around the same impact on the motor.

Next I ran codes. KOEO, I got code 95 - fuel pump secondary circuit failure. Don't know what to do about this. Fuel pumps comes on at the turn of the key, relay clicks... KOER, I got 11 (pass code), so nothing there.

Then I hooked a fuel pressure gauge to the schrader valve on the fuel rail, and at idle pressure was a steady 35 PSI. I also removed the vac. line to the FPR while running to see if gas came out. I checked for vac. leaks as well.

Now not sure what to check now. I've checked everything I know to check, but nothing works....

Ford Ranger / B-Series :: 1994 V6 Idles Low - Surges Up / Down - Black Smoke Puffs And Smells Like Gas

I have a 1994 Ford Ranger with 4.0 V6 Automatic. The problem is when it idles it idles low and surges up/down and pushes a very small amount of black smoke puffs and smells like gas. I have installed new coil, new wires, new plugs, new ect, new crankshaft position sensor, and new maf. It has new intake manifold, new injectors, new alternator and it still does the exact same thing. Nothing is phasing it. I ran the key on/engine off test and got egr codes and a map sensor code, then ran the engine running test and got 998 and 126 code. The 998 code says that its basically a hard fault/ have no idea.

I do know this is a donor engine out of another year not sure what year, but i know when i ordered the coolant temp sensor the only ones that would plug into it are the years 1990-1993. Now here's my other question, why would the computer give me a map sensor code when truck doesn't have a map sensor? It has MAF sensor, and why egr codes? The truck doesn't have egr and never came with it. I do know I've unhooked battery and replaced the maf and its like it doesn't even recognize it? Could it be the ecm/computer bad or needs flashed?

Ford F-150 - 1997-2003 :: 1999 4.2L - Hot Start Rough Idle / Surges Sometimes

I am new to FTE and have a question about my 99 4.2l. After it warms up, i can shut it off and about 30 mins later try to start it again and it will idle very rough and sometimes stall. I also noticed that it surges sometimes with just off idle throttle when its cold. I am not getting any codes thrown, here's what I've done so far: cleaned the maf and throttle body, and it didnt work at all. I did convert my cht over to ect by using the plugged coolant outlet on the lower right side of the intake manifold and extending the connector wires which actually solved the problem a little bit but it still does it from time to time.

More info about the cht to ect conversion, but after reading that ford did away with them in later models i wanted to do the same while at the same time making it so much easier to swap it out if ever needed. No more getting under the truck. And where im at cht's are kind of hard to come by without having to order them Anyway, it worked flawlessly! I only had to extend the wires by about 8", wrapped them and ran it along side the injectors for a clean factory look. Ill try to post pics soon...

Ford F-150 - 1997-2003 :: Idle Rough / Nearly Dies / Surges Above 80 Degrees

'1999 F150, 5.4L, 85K miles ....

Fuel pump failed last year, had it replaced. Ran fine for a week or 2, then one day went into limp-home mode. Mech replace fuel pump relay, again ran fine for a month or so. Now when the ambient temp gets above 80F or so (yeah, it has already this year - I'm in Central TX), engine at full op temp, I'm experiencing some sort of heat-soak issue. Engine runs fine when cold, and at normal op temps on the road, but if it is parked for 15 - 20 minutes then restarted, the idle goes all funky - nearly dies, surges, etc. for a minute or 2, and then it seems ok.

I would go back to the same mech, but he had to close his shop due to health issues, so I'd like to see if I can resolve this. So, it is definitely heat-triggered, and "seems" like a fuel issue, but of course it could be some electrical contact having difficulty above a certain temp.

Ford 6.0L Power Stroke Diesel :: Surges / Buck At Acceleration - Gallop / Miss / Stall At Idle?

I've seen the gods of the diesel engine do some amazing things on these forums, so after a year of pulling my hair out, I've signed up to try this myself.

This time least year,I bought a 2004.5 6.0L F-250 with 196k on it to haul around the state for my new business. At this time, I knew nothing about diesel engines AT ALL WHATSOEVER, but I've never been afraid to tackle anything and mechanics are not totally foreign to me. Not to mention, I was hoping everything might just go peach-ily for at least a couple years. (for what it's worth, My dad and his family are mostly shade tree mechanics and I'm a power plant operator so mechanical concepts are not totally foreign to me, just never had a diesel before)

To begin, I purchased the truck and everything was fine for about 2 weeks. Then abruptly one morning I noticed a couple of hefty surges on the way to work. Then, on the way home I thought all was well until about half way home, it did it again! as I was pulling up, it galloped once I pulled my foot off the pedal. like ba-DA-DA-DA-da-da-da-da-da-da-DA-DA-DA-DA-DA-da-da-__ and then STALL! Shaking with concern over potentially an awful purchase, I turned the truck back on only to find... that it's fine?!?? No problems for the next two days and then it happened again. then good for a week, then again. then good for 2 weeks, then again. so then I bought auto enginuity and an edge insight to do some troubleshooting. Let that sink in as I explain it's history a bit.

-All but one injector is ford remanufactured the other is stock (was never told which one)
-replaced head gasket with another OEM
-ARP Head Studs
-EGR delete
-HPOP AND STC fitting both replaced
-FICM replaced
-Oil cooler replaced 50k ago
-ICP and pig tail replaced right before my purchase
- Has been through roughly a handful of ICP's since I've had it (I'll explain)
-I've cleaned the EBP tube a lot and updated it to the newer ford sensor with the flare fitting

-I use Rotella T6 5W40 and CAT ELC-1 Coolant.
-Deltas are under 10 at normal driving
-I typically drive under 2200 rpm until warm then like a banshee at operating temps.

Now one year later, its not fixed, but I feel like I'm close.

The DTC's I have seen are ICP sensor circuit intermittent (I think po2884) and Power Blance contribution failure from cylinders #2 #7 and #8 but never at the same time.

Every time I replace the ICP, it will be problem free for about 6 weeks and then it will return full force (surging and galloping when warm about 50% of the time)

During a possession I see the following:

*Cylinder power contribution test yields no issues at idle or when cold. when "possessed", the whole baseline across all cylinders goes up and all cylinders dip and return at random. none singled out

*ICP voltage fluctuating from ~.6v to 1v (.24 @koeo) *Also during a surge*

*ICP PSI dancing up and down ~600 to 900psi (0.0 @koeo and ~500 at normal warm idle) *Also during a surge*

*IPR% bumps up and down ~25% to 30% (15%@ koeo and 23% at normal warm idle) *Also during a surge*

*FICM Voltage anywhere between 47.5v and 49v

*EBP is normally 15-20 psi

*Boost is 1-7 normal and is not affected by "possession"

These numbers have taken a long time to get since it will only be possessed for about 3-10 seconds at a time and then will disappear for days. The stall has only happened about 5 total times in a year. The surging is much more frequent. I usually get a buck or 2 on any given trip that is longer than a half hour but NOT IMMEDIATELY AFTER AN ICP REPLACEMENT.

On one occasion, I noticed that the ICP PSI actually tanked to about 350 right before the IPR went from 25% to 40% right before a posession. I was driving about 35mph through town at the time.

Here's my thoughts...

- Did that one occasion clue me in to an intermittent HPO system leak causing the truck to briefly over-compensate by spiking the IPR?

- Is my ICP pig tail jobby done incorrectly? If there was a short, wouldn't I see the volts drop to 0? I have another one and will replace to rule it out.

- I have yet to test my fuel pressure, but I figured if it was low, I would have lost injectors by now. (I replace filters probably too often but next empty tank, I'm dropping it and checking the screen and strainers)

I should also mention that I have buzz tested the injectors and I can hear each one clear as day, and that for REALLY long trips, it actually returns to normal. In other words, my window of death is between 30min and 2hrs of driving; invincible after.

Ford - Ranger :: 1991 V6 - Antifreeze In Exhaust

I have a 1991 ford ranger 4x4, 4.0 v6. 190,000 miles. Runs great and even gets 18-20 mpg on hwy trips with a 1200lb camper. I have been using small amounts of antifreeze for the passed year with no leaks. Lately much more, sometimes a 1/4 gallon in 400 miles. 4,000 miles ago was having a miss and changed the plugs that had 30,000 miles on them. Miss went away but came back 2000 miles later. Changed plugs again and wires and miss went away. Now about 1000 miles later no miss but using more antifreeze. The plugs each time looked pretty good. The last time, when I changed the plugs and wires, it started blowing a lot of white smoke on initial start up for at least 30 minutes at idle, then just water dripping off the tail pipe.

It did that a few more times and then stopped. When it sits for a few days I can see the smoke on start up for a few minutes only. I just took a 400 mile trip with the camper and it ran great except for the using antifreeze. I took a compression test and they are all within 7 lbs of each other. I did a block test using the blue fluid in the proper tester to check for exhaust fumes in the air in the radiator. The fluid stayed blue indicating no exhaust fumes in the radiator. I hooked up a radiator pressure tester and pumped to 20 lbs, didn't drop for 30 minutes. On a cold engine pumped radiator tester to 10 lbs, disengaged ignition and turned engine over 5 different times 10 seconds each. Needle stayed at 10 and didn't fluctuate.

I hooked up a vacuum gauge, teed into the line from upper intake manifold to brake booster. I am at 5000 feet altitude so deducted 5 from all the results of the tests I read about online. Everything seems totally normal with vacuum. Needle is steady at 16 at idle, 17 steady at 1800 rpm and 2500 rpm. At 2500 rpm for 15 seconds and release throttle it climbs to 19 and then back to 16. If intake manifold gasket is leaking would it show up in vacuum test?My first thoughts were head gasket but after reading some forums I am wondering if it could be intake manifold gaskets. I am not sure about the configuration of the water and intake ports.

Seems like antifreeze is getting into the combustion but no combustion getting into the antifreeze.I called Ford dealer and they said could be a thermostat housing or sensors around that area on the intake manifold or the water pump and of course wanted me to bring it in for testing. It does not make sense to me how any of those could cause leaking into the manifold? How that could happen and how to check for that?So....Is there any way to know if the antifreeze is coming from either of the intake gaskets or the head gasket or a cracked head? If it was a cracked head or head gasket I was thinking of trying a sealer, steel seal. If a manifold maybe a product with copper in it. If that didn't work then I was going to tear it down.

Golf IV R32 :: Uneven Idle / Slight Surges Under Acceleration

OEM plus. 93k. Um tune. Evoms intake.

Did the plugs and coil packs, fuel filter, cleaned throttle body (Did a vagcom alignment) as well as some other insignificant maintance.

Car ran fine for weeks after, but recently it has started to bounce around randomly at idle. Like 650rpm(normal) for a few seconds. Then it will Slowly climb to 800rpms, hold there for a few seconds. Then back down to 650ish for a few seconds, then back up to 800 for a few seconds. And so on. It's very subtle and very random. Then sometimes when accelerating, I can feel it in the gas peddle. Like a slight pulsing power loss. Very slight and of a similar rhythm to the idle issue.

I do have a check engine light for Load Calculation cross check-p1143-001 upper limit exceeded. But that has been a battle I have been fighting for a year or so, and I think that is some kind of vacuum leak, but this rpm issue just started a few weeks ago. The only thing I was thinking so far is that when I was doing the plugs and coil packs, I noticed that there was a slight bit of what looked like dielectric grease on each coil pack already from the factory. So I didn't put any more in the coil packs sleeve part that fits over the plug. So was that a mistake? And if it was a mistake would this be a symptom of that?

Volvo - 240 :: 1991 - If Shuts Off For 30 Minutes Then Stalls Immediately After Restart?

my daughter has a 91 volvo 240 with a 4cyl and auto. roughly 100000 miles. it starts and runs fine but after driving it, if it is shut off for less than 30 min, then she tries to start it again, it stalls immediately. she can keep her foot on the gas slightly and drive it the distance of a parking lot, the car will run fine and not stall. i was curious if a tune up would fix this or if there is a smaller fix such as a sensor.

Ford Ranger / B-Series :: 1991 - Turns Over But Will Not Start

My 1991 ranger with a 4.0 turns over but will not start. It acted like it ran out of gas put again seems to do ok then it did same thing it sat over night then would not start so I thought I would put some gas in the intake so it starts ran real rough but smoothed after a few minutes ran fine after that next morning same thing no start did same put gas in intake at first no start just turned over didn't even try let it sit for awhile then tried again it fires up ran rough but ran now I get nothing just turns over pulled codes 22and 122 replaced both had ignition mod checked its good new coil pack no change so at this point i hear fuel pump kick on fuel getting to fuel bar but seems a bit week on pressure going to get pressure gauge and see what it says but in the meantime I am loosing my mind...

Ford Ranger / B-Series :: 1991 2WD - EEC Fuse Keeps Blowing

My dad's 1991 Ford ranger 3.0 2wd just died on him when he was driving home and I checked to see if the truck had a spark and it did not so I replaced the ignition control module, then ignition coil, then distributor and rotor cap(plug) and I put new plugs and wires on it a few months back too. I also checked to make sure that the timing chain was working as well (while I had the distributor cap off). Then I realized that the EEC maxi fuse was blown. I then found a fourm that said it might be the relay so I replaced the EEC and the fuel pump relays while I had them both out. Every time I put a new 30 amp fuse in the EEC slot and turn the key to start it the fuse blows and the truck won't start. What might be wrong?

Cavalier - Chevrolet :: 2002 - Surges Forward While Idle & Rev Up To 1500 Rpm?

I am having issues with my 2002 chevy cavalier.

The car occasionally surges forward while idle and revs up to 1500 rpm approximately occasionally when the air conditioner is on... if the brake is not applied I move forward.. the lurches are continuous every 3 seconds or so.

I am getting a code for an evap leak.. I have replaced the purge solenoid valve, gas cap, and checked all connections with no luck... slightly decreased gas mileage has occurred.

A little bit of a slick substance has been leaking from the car.. it has the consistency of water, but leaves a slight brown tinge on concrete.
