Cavalier - Chevrolet :: 1988 - Revs Up On Starting - Dies Down To Low Idle To The Point Where It Shakes A Little Bit
I recently bought this cavalier about a week ago its and 88 automatic trans with 1.8 4 cylinder I thing not that it matters much. I noticed the exhaust had a smaller pipe from the manifold and the rest was strung with a bit bigger pipe and was attempted to crimp the pipes togather it was loud so I crimped thhe pipes better and used exhaust glue to patch the holes it runs better now to a point. but when I start the car it revs up a fair im guessing 3 grand since I have no rpm gauge but then it dies down to a low idle to the point were the car shakes a little bit.
with the exhaust fixed I can get it up to 20 kilometres an hour with my foot off the gas when I turn fully it wants to lurch ahead/backwards. when I took it out for a highway drive today I came to a stop sign so I slowed and stoped and the car stalled out. started no problem. but I also tried later putting it in neutral and it doesn't stall as I role to a stop it doesn't shake in neutral. I would like to have this fixed but I need some pointers as of were to look. im not sure if this means anything but when I got the car it had a bad enough radiator fluid leak at the hose meeting the heating car on the engine side of the fire wall I repaired that and no longer leaks.
Volvo - 850 :: 1997 Started Stalling Intermittently When Idling
I have a 1997 volvo 850 that has started intermittently stalling. It usually happens when i'm idling, like at a stop sign or traffic light, but recently it did it on the freeway. I have taken it 6 times to the mechanic (5 times to one and finally having learned my lesson the last time to a new one) and they say it is one of 4 things, but can't figure out which of those 4 things it is until it stalls on them. which it hasn't done. it acts perfectly when at the mechanic's and then they always give it back to me, only for it to happen again. the last time the car ran beautifully for 6 weeks before stalling out on me again....... oh, and once they replaced my fuel pump which seemed to work for a while.

1998 BMW 540i started stalling at idle.First time was after filling up with gasoline. The car restarted after two attempts to start then it kept stalling. Okay for a couple of weeks.Then the auto glass people plugged something into my cigarette lighter and it drained the battery. The had to jump start the car. Later the car stalled while coasting downhill into a parking lot. I took it to the shop.The mechanic scanned the codes and found a sensor that was "borderline" weak. They replaced the sensor. The next day the car stalled while waiting at a stop light. The car restarted okay after two attempts.Later the same day the car stalled at another light, downhill again. This time the car didn't restart after three attempts. Fourth attempt I gave it a lot of gas to keep it going. It fires up okay, but stalls.The mechanic checked the wiring to the replaced sensor, but couldn't find anything.The car stalled again going uphill out of a parking garage. It restarted and This Time the SERVICE ENGINE SOON light stayed illuminated.
View 1 RepliesFord Excursion :: 2003 V10 Truck Started Stalling At Irregular Intervals
I have a 2003 Excursion 4X4 V10 (6.8l) gas with 130K.
About six months ago, the truck started stalling at irregular intervals. The truck runs fine for weeks at a time, but will suddenly die. This happens at idle, and under power. After stalling, the truck usually starts back up, but there has been a few instances where I thought it sounded fuel starved. It has stalled as many as four times in a row (within 15 minutes), but shortly after it runs fine again.
I researched this board, and tried the following: cleaned the MAF, and replaced the IAC Valve.
But, it stalled again, so in late February I took it to the dealer; a AAA approved repair facility which means they guarantee the fix for two years.
The dealer claimed to have pulled a P0231 code. As a result, they replaced the fuel pump and assembly, along with the fuel filter.
The truck ran fine until two weeks ago, then it went thru a series of stalls again. In each instance, the truck started right up, and I drove it to the dealer.
The dealer took it in again and had it for six business days, but they could not replicate the issue. I suggested they test the PCM/fuel relay and the signal going to the fuel pump - they said everything checked out okay. No charge, the ticket remains open.
What could be causing this? I am not too good with electrical stuff; in fact, I know very little. Another member explained a way to test the signal at the time the truck stalls, but I am not sure if I could competently do it. I am thinking I need to start replacing part after part until it stops? I don't mind doing that, but would need to know which parts to focus on. Should I start with the MAF? I cleaned it, but do not know how to test it.
Ford - Explorer :: 1993 - Intermittently Started Running Very Rough
I have a 93 Ford Explorer, manual transmission. About a month ago it intermittently started running very rough. I does this wether the weather is rainy or not. The engine has done this when it just started up, cold, and when it's been fully warmed up. I have been able to drive it, but it has been quite a challenge. When running, there is a very noticeable noxious exhaust smell. The check engine light has come on some of the time. When the eec codes were checked it only revealed 522, the car wasn't in park or neutral when running the test.
I have tried clearing and rerunning this test several times, yet 522 still shows up. No other fault codes. Don't know how this would cause engine to perform so bad. The fuel tank has been near full when it happened so I believe the gas to be good/ no water. The engine has a lot of mileage on it, over 200K, so I'm not sure if something inside could be malfunctioning, but don't know how to check. The car will run for days very smoothly before this happens again. I have changed plugs, wires and the pcv valve and it still occurs. It's like the engine is hitting on one cylinder when it happens.
Subaru - Outback :: 2004 - Motor Won't Stay Running When Car Started Intermittently?
I have a 2004 Subaru Outback. This fall I started having intermittent problems starting the car. It would run like a champ, no problems. Then every once in a while when I would try to start it, typically happens after it has sat all night, it would turn over just fine, motor would catch, then the motor would quit running (almost immediately upon start). It is kind of like the old days when your carburetor was not adjusted quite right and you would have to keep one foot on the brake the other on the gas while stopped at a stop light to keep the motor running.
The first time it happened we added "heat" as we thought it might be water in the gas line somewhere. It started, then ran just fine. This winter the problem started recurring more frequently. We added injector cleaner, it seemed to work a bit, but did not solve problem. We took it to the shop, and they could not figure out what was going on as nothing is registering on the computer and the car would start just fine for them. Brought the car home it worked OK for a week or so, then started up again.
The motor would catch then would quit running almost immediately. We were able to get it running good enough to get it to the shop (kept one foot on gas at stop lights, etc so would not kill). My car has been at the shop for two weeks now. It finally misbehaved on their watch, and they replaced a sensor, but they are not sure it fixed anything. They are keeping it so see if they can get a better diagnosis.
My first thought was the gas pump, but they said they had never seen a subaru gas pump fail and usually when a pump goes out, it goes out. They thought it could be electrical, but not sure as the problem is so intermittent. I would like to get my car fixed and back home. It's a great car; when it is running it runs great. The shop we work with is very good, and they are reluctant to start just replacing parts if it is not going to fix the problem.
Oldsmobile - Cutlassciera :: 1996 / 2.2 L4 Running Rough Idle And Stalling
1996 / 2.2 L4 / 186k / Upper engine rebuild 30k ago
Car was driven on a errand by my mother. Upon trying to leave for home, the car started running very rough, and stalling. From the description she gave on the phone, it sounded like a plugged up exhaust. I told her to get some fresh gas and ease it home after.
When I checked the car for codes, I got 2. A P0300 and a P0122. Okay, so the throttle position switch has taken a dump, that's easy enough. The car has 186k miles, but my constant nannying usually soothes her, so surely that's all, right? God, I wish that turned out to be true.
I pulled the plugs, and #4 was gas fouled and sooty, #2 and #3 looked lean, and #1 was partially wet fouled. There was also gasoline in the oil. When the car would run, it would run the gambit from idling semi rough then stalling out and refusing to restart, almost like it was flooded, to idling scarily bad and no pedal response, to running too high of an idle and idle searching.
Since I have:
Replaced the TPS
Replaced the IAC
Replaced the CTS
Replaced the MAP
Replaced the ICM
Replaced the FPR
Replaced both ignition coils
Replaced plugs and wires
Replaced the fuel injectors
Replaced the PCV
Replaced the fuel filter
Checked the pintle on the EGR (looked good, cleaned)
Checked for Vacuum leaks (as best I could)
Checked the Fuel pressure (40 PSI) (drops to 20 after shutoff)
Checked for exhaust restriction (ran open exhaust manifold)
That brings us to today. New injectors just in, and the engine will run, but rough and loud. It almost sounds like the firing order is off slightly (I am using 1342 or from L to R 4132) and throttle control is almost non existent. It also shuts off when its warm almost like its flooded. No codes are showing. (despite discovering a sensor in back being unplugged and the O2 sensor being unplugged at times).
Audi A4 :: 1997 Stalling - When Started Up And Left To Idle All Of A Sudden RPMs Drop
I have a 1997 Audi A4 that has been acting a little bit strange lately. When it is started up and left to idle all of a sudden the RPMs drop from around 600-800 to 100-200 sometimes rebounding back up and sometimes the car just dies. This also is happening while I am driving and stopped at a stop light for a short time. It will idle fine then suddenly drop RPMs and if I don't give it any gas then the car usually dies. I have just had some work done on it to try and fix this problem thinking it was the air flow sensor (or something like that) but apparently that is not the case.

I have a 2010 F150 5.4 with 43k miles. When approaching traffic lights or making a turn and you are approaching idle speeds the truck will start to stall out then ultimately shut off, causing me to loose all functions. It has cause my wife to almost get into a couple of major crashes. Sometimes when trying to start it back up it acts like it is not getting any gas it just keeps turning over. I took it in and it could not be diagnosed because they could not duplicate the problem. This will happen for a couple of days and then be fine for a month or two then start right back at it.

Have a 2007 and everything was running fine all day today. Stopped at home for a few hours and went back out to run a few more errands and my truck started running poorly, dashboard lights were dimming, and the ESC OFF & ABS dummy lights came on as well as the red battery light. Managed to turn around and make it back home. Sounds like my battery needs replacing? Hopefully its just the battery and not the alternator.
View 22 RepliesFord 7.3L Power Stroke (1999-2003) :: Engine Just Started Stalling Off Idle And Restarts Easily
Truck has been driving great for a long time and this afternoon after driving fine to work just died 3-4 times while trying to accelerate from idle. Engine restarts easily but the power is soft off idle, the injectors sound noisier and then quiet down and will accelerate decently once rolling but something is off I can tell.
Fuel pressure is read post filter and is good. Truck is well maintained with all the basics replaced in the last couple years. Could this be CPS going out even if it is only a couple years old? IPR is new in the last year, ICP sensor isn't leaking. Most recent change was a full tank of fuel yesterday afternoon and on a whim performing a boost leak check which was all good.
Ford F-150 - 1997-2003 :: 2002 - Truck Is Hard To Get Started And To Keep Running
Sometimes the truck is hard to get started and to keep running, Once it warms up it will run fine. The next time it is started it will start fine but when you are going down the road if I try to accelerate it will start backfiring and not pick up any speed. I am getting a lean code on both banks. I have changed the IAC, the throttle position sensor and mass air flow sensor. 2002 F150 with 6 cyl
View 1 RepliesDodge - Dakota - Radiators :: Truck Started Running Hot / Foam Coming Out Of The Overflow
we had a shop replace a thermostat in oct 10, last week our truck started running hot so we put in about 3 qt of 50/50 coolant. it returned to normal temp the next day we noticed some foam coming out of the overflow. when we opened the hood it looked like a brownish/red color and is a thick foam. When taking it back to the garage they cannot tell what it is. They have tried to flush it out and say they put in 3qt of fluid and only get out 1qt. It can be chunky at times. What it could be?
View 1 RepliesFord F-150 - 1997-2003 :: Truck Suddenly Started Running Rough / Too Many DTCs All At Once
I have a 2001 F150 4.6L auto. This truck suddenly started running rough. Cleared all codes and re-scanned after starting truck. The codes are as follows; P0135, P0155, P0443, P0740, P0743, P0758, P1451, P1460, P1747, and P1760.
My question is; is it normal to have this many DTCs come up at once? Could my PCM be faulty causing this problem? Can you swap a pcm from the same year truck with the same options without reprogramming?
Toyota - Avalon :: 2014 - Hesitation Nearly To The Point Of Stalling
2014 Avalon Limited, once in a while (mainly when taking off) I get a hesitation nearly to the point of stalling, then it picks up and runs normal. When I mentioned it to service advisor they said it was bought on by the AC fans kicking in. Now that the colder weather is starting and I'm not using the AC I've noticed it hasn't made any difference. Other than that, I love the car.

I have a 92 ranger 6cyl 4L. The truck stopped running while driving then kicked on again, it did this several times over about 20 minutes then finally died and now I can't get it started. I recently replaced the fuel pump and filter and spark plugs and wires. I get spark if I ground the plug and some gas will pour out of the fuel pressure test valve when I stick a screws driver in. When I check engine codes I get an all pass. Truck will turn over and sometimes run for 2 or 3 seconds but that is it.
View 2 RepliesFord 6.0L Power Stroke Diesel :: 2005 Missing / Truck Started Running Rough
So I have been fighting a rough running, missing problem. My truck started running rough one day on the way home. I got it scanned, it showed injector contribution balance 1&2. Made sense to me that it threw those codes. I replaced 1 and 2 with oem replacements. Got that all done, truck still ran like crap. I changed fuel filter with motorcraft ones and drained the water separator. That didn't work. I am getting it scanned again, so i will have codes shortly.
Also, for a while it would run with absolute no problem. It was intermittent like that. Run bad run bad run bad and then one day run flawlessly. I though it was electrical. Checked all the common places for chaffing, saw nothing. Even did the wiggle test while it was running, no change. But it hasn't been intermittent for a while now.
Ford 6.0L Power Stroke Diesel :: Rough Running / Truck Started Bucking And Hesitating At 45 MPH
Since our weather has returned to the cold side......my truck has started bucking and hesitating at 45 mph with EOT @ 130 and ECT @ 140. I can gas on it and it will clear up/let off and it would start up again once it gets below 50 mph. Once the deltas reach 150+ it clears up completely. Its never done this until this week. FICM volts are steady @ 48V. What is causing this or what to look for?
