Volvo :: 1990 - Long Crank Then Eventually Start But Run Real Rough
1990 Volvo 760 4 cyl. Turbo. Drove the car to work, everything fine. Got off work, car wouldn't start. Cranked but wouldn't start. It was getting spark. Changed the fuel filter, it ran perfect for a month. Drove it to town a month later, shut it off, then trying to start it, would crank and crank eventually start but run real rough. We got it home....barely.
Replaced the fuel filter again. Still wouldn't run right.
Replaced the fuel pressure regulator. Same problem.
Replaced the throttle positioning switch. Same problem. Replaced the air control valve. same problem.
Found out that this car has an on board diagnostic doo hickey.
Found out how to check each sensor and component individually.
All sensors and components are working. Checked both fuel pumps and they are working. If I unplug the air flow sensor and the air control valve sensor, I can start the car using starter fluid and it will idle all day with out missing a lick.If I plug in either one of the sensors, it will kill it immediately.I don’t know what else to do to make this machine run.
Ford F-150 - 1997-2003 :: 2002 - A/C Causes Rough Idle And Stall / Sputter And Die On Restart
I have a 2002 4.6L FX4. When I run the A/C for an extended period (say 15-20+ minutes), it will start to cough and sputter and eventually just die. It will restart but run rough and cough, sputter, die.
If I turn off A/C and let it set a while, it runs fine. No check engine light. Possible EGR problem????
Mercedes-benz - E-class :: 1991 - Sputter And Eventually Stall / Car Won't Start When Hot
when the temperature is above roughly 60 degrees, I can drive the car for a short while, even a few miles, and it will start to sputter and eventually stall. At that point the car won't start, it turns over fine, but sounds like it's not getting any gas. If I wait 15-20 minutes it starts fine and will repeat the same process. Is there some temperature sensor or something that prevents the engine from starting after it gets hot, or is it something else. The temperature gauge doesn't indicate the engine is hotter than normal. I've taken it to my car shop twice and they haven't found anything. 1991 mercedes e300...

My car started a rough idle last night.... Pull to stop light, in gear, a/c on #1 and car shudders and acts like it's going to stall..... Went away as I drove a round a bit.....back this a.m. (after the warm up program ran) drove it a bit and was sporadic.....and even went away...then came back.....
Its worse when car is at stop and in 'D'.....little better with a/c off and/or in neutral......it finally threw the CEL today....... I had the fuel pump recall done about a month or two ago, car has 36k+ on it...... Anything I should have the service dept look for aside from what the fault codes might read?

Golf/GTI VI :: 2011 - Rough Idle And Stall
So this morning when I went to start my car for work, it wouldn't idle and was misfiring badly, also has a very loud noise coming from the valve cover. The car has under 40k miles on it and is CPO, so it'll be towing it to the dealership today to get check out. The car ran fine on friday when i parked it.
Here is a vagcom scan I did this morning also.

SC/SL/SW :: 2002 Saturn SL1 Won't Start - Running Rough And High Idle
Recently replaced spark plugs and wires on 02 SL1 with 209K miles. Was running rough, rough and high idle, almost died on me driving home one night. After replacing everything, car still wouldn't start. Spent some time on the forums and some suggested a leaking intake manifold gasket, so I changed that out as well as the coolant temperature sensor. Still it won't start. I am getting good spark at the plugs (coil arcs across the posts when plugs wires are off).
Really not sure where to go next with this. I can hear the fuel pump hum when I turn on the ignition, and I get a good spray at the fuel rail. Basically I turn the key and it cranks, sputters, and will almost catch, but then not. What next??
Camry :: 2002 SE - New Engine Mounts Now Rough Start And Idle?
I have a 2002 Camry SE (V6) with approx. 180K miles. The Engine mounts were shot so I decided to change them. I am a reasonably qualified mechanic (FAA Aircraft Mechanic) and perform most my work on my cars so didn't think this would be a big deal.
My procedure was to jack up front & put frame on jack stands then removed both wheels. Then with hydraulic jack and blocks under oil pan I started by removing all or the three lower engine mount hold down nuts (3 on bottom, 1 on top of each. NOTE: I changed the dogbone first which took 5 minutes.
I then jacked up engine about two inches or so and pulled out each old mount, then lowered engine back down making sure everything lined up as best I could. Then finished by tightening all of the nuts. Done. ....or so I thought.
When I went to start, the engine cranked but with a an unusual vibration and generally rough idle, more noisey than usual. When I drive it shift fine and everything works, just unusual vibration and noisey inside car.
I also used my BOSCH code checker and got ZERO CODES.
What is even more unusual is the engine when you are outside the car listening sounds fine. Just sitting inside do I sense the unusual vibration and noisy idle.
I checked for loose vacuum hoses, anything obviously pulled loose, etc and found nothing.
Again the car started and idled fine before the engine mount change now starts kind of rough and is noisy [inside car] but quiet outside.
nothing really changed except the moving of the engine block up and down to get the old mounts out.

View 7 RepliesToyota - Camry :: Rough Idle - Parkway Stall
My 2001 toyota camry is great but has an intermittent, annoying problem no one can diagnose or correct. If I drive for a while at top highway speed (say 65mph) and then have to come to a stop (to pay toll or stop light) I get a very rough idle and then the car stalls. Have had new plugs, wires, coil, radiator already done to solve problem. Check engine light never comes on. Can also drive lengthy trip and it doesn't happen.
View 18 RepliesNissan - Pathfinder :: 2002 - Slowly Crank And Eventually Start
Will try to sum it up: Most of the time, the thing starts like a charm, first try. Every now and then, though, I'll turn the key and either a) nothing will happen or b) it will slowly crank and eventually start. If nothing happens, I have always been able to try again seconds later and everything works OK. Have been through several batteries. Current battery checks out OK, as does starter and alternator.
A short circuit, perhaps? If so, how would I check it out? Problem with taking it to a mechanic is, most of the time all is OK. No pattern as to when the trouble will occur (has yet to happen with vehicle in the shop, of course).
Ford - Escape :: 2004 - Rough Idle At A Stoplight Like Going To Stall
Last week I had the plugs, coils, valve cover gasket and fuel filter done my 2004 Ford Escape when the engine started misfiring and today it started to idle rough at a stoplight and it seemed like it was going to stall but didn't. I had it sit for about an hour and a half and the it did want to turn over like the battery did have enough cold crank to it but it did after a couple of times. It has come and gone for the last couple of hours. No warning lights are one either. It seems pretty close to what it was doing when it was misfiring. What it may be?
View 10 RepliesNissan - Maxima :: 1993 - Rough Idle And Stall After Warmup
1993 Nissan Maxima. Great little car except when engine gets warmed up it begins to run rough and dies. At idle, when accelerating, while maintaining speed. Since its a manual it is a simple matter of dropping into neutral and it fires right up again... no problem. Then stall repeats. Went through routine steps checking plugs, filters, wires, sensors etc.. The O2 sensor (only one) is gone - as is the converter. At some point someone replaced it with a straight pipe.
After not finding a obvious answer, I began to ask around (auto-part stores, neighbors, some patrons at the saloon). Conclusion... OBD failure causing a "kill" routine which shuts off the engine. When I restart, it resets. Once it fails to enter a static state (engine is warm) it kills again. I replaced the computer with a used one "known" to operate (so the e-bay seller said) Installed it and bingo, car ran like a top for 15 full minutes - best ever. Then after 15 minutes or so, suddenly began to run rough and stalled twice before I got back home. I runs now just as before (but oh those glorious 15 minutes).
Ford F-150 (2009-2014) :: Idle Rough Sometimes Almost Feeling Like It Was Going To Stall Out
I have a 2013 with the 3.7 in it with 24,000 miles on it. I bought the truck used with 8,000 on it was a pre-Owned certified and it already had a k&n air intake which I know it's not needed and I would much rather have the factory intake instead.. 7 months ago I took it to the dealer because I noticed at stop lights it idled rough sometimes almost feeling like it was going to stall out so I took it in and they said that the motor was getting to much air and causing it to run like it was and they said the cooler weather was making it worse and said it should get better when it warms up and they said it wouldn't hurt anything... Well I live in Florida and it's been in the 90s and it still idles like crap you can feel the vibration through the truck...
And it's so aggravating and annoying and I wish I had a stock intake that I could install on the truck to see if it fixes the problem but I don't and I've researched the problem and have seen people with the same issues without the k&n air intake and I've also been told that the stock air intake gives the motor just as much air as the k&n so with that being said did the dealer take the easy way out and blame the intake or should they be responsible for installing the factory intake back on since they made it a certified pre-owned with the k&n on the truck? It's been frustrating because I don't know a whole lot about gas motors.. And I'd like to get the problem fixed while I still have warranty ..
Ford F-150 (2004-2008) :: Rough Idle / Truck Wants To Stall
Let me describe this perplexing issue. I have a speratic rough idle problem. When it happens it's almost like the truck wants to stall. Once going the truck is fine. There has never been any acceleration issues, but for a short time the truck would kind of lunge off idle. It hasn't done that for quite some time. I've replaced the fuel filter. There are no vacuum leaks that I know of. I've tried higher octane fuel. I've tried injector cleaner for a month. What should the fuel pressure be and what is the test port located? Is the fuel pump in the tank? If so, whats that big log looking thing behind the gas tank that the fuel lines run to? Also, there are no MIL codes...
View 14 RepliesGolf/GTI VI :: Extremely Rough Idle And Engine Stall With Clutch Depressed
This morning when I started my car the RPMs were all over the place. The engine would rev to just below 2k and then drop, as it it were gonna die and right before it did, it would rev back up. Then, when I tried to move it, it would not accelerate and would hardly move and while coasting it dies if the clutch is depressed. The car does not die when idling (albeit a very rough idle) but it does when it is moving.
It flashed a check engine for a few seconds at one point but went away and has not come back on. I am running APR Stg 1 and a Carbonio intake. I switched from 93 octane mode to stock and nothing changed.
Ford - Explorer :: 1995 - Rough Idle / Stall And Choke A Little When Cold
My truck is a 1995 Explorer 4.0 150,000 miles, 5 speed.
Problem - Rough idle : when cold it's worse and will stall and choke a little. When warmed up it just has a rough idle but will not stall and stays at a pretty constant RPM. It's very tolerable when warmed up but still not right. It drives fine once off idle. No black smoke that I can see. Power may be just a little off but I would not bet on it. MPG seems about normal but haven't been on a long enough trip since problem started to tell for sure. Also longer than normal cranking on occasion.
Diagnostics so far : Fuel pressure is at 32 PSI, vacuum off regulator it's at 40 PSI. Not sure about key on only as I don't trust the autozone loaner gauges. You have to fiddle with it each time before it will read. Leak down after 30 minutes was about 4 PSI
No Check engine light ever. KOEO test shows no hard or on demand codes, I get the 111 pass. From CM I get 336 and 45.
336 is EGR related and my looks pretty rusty. I put a vacuum pump on it while running and the EGR held vacuum but had no effect at all on idle, I was expecting it to get worse as I opened the EGR so it may be stuck.
Searched high and low for vacuum leaks by ear, visual and with starting fluid all turned up nothing.
Actions so far : Replaced plugs, wires, IAC, and fuel filter. Cleaned MAF sensor and throttle body plus ran lucas fuel injector cleaner through it.
Next steps : I've got the EGR but it's so rusty I am sure I'll break the tube it bolts to plus I don't know it that alone will cause the rough idle. Will the DPFE sensor and/or EVR create a rough idle yet not turn on the CEL?
Thought about changing the fuel pump and/or regulator but the numbers are not terrible. Agree?
Thought about changing the intake gaskets but don't see any leaks.
Ford Super Duty (1999-2016) :: 2002 F350 V10 Won't Start / Rough Idle
I have a 2002 F350 with a V10, this just started happening where at times the truck will turn over but won't run... after a few times of trying to start it I pull the key out let it sit for 5 seconds then put the key back in and runs perfect..... now at the gas station the other day it started but ran like it was on 4 cylinders... I turned it off and restarted it and runs perfect. Heading to Kansas next week to pick up my boat and don't need problems....
