Intrigue :: Can't Stay Running After Starting When Engine Is Warm - No Codes
I have a 1998 Intrigue with over 225,000 miles. It seems to run well for the most part. However....
After I have driven the car for a while and gotten it up to temperature, if I stop and let it cool for a while, when I go to start it up again, it will start easily and then immediately die. Almost like the fuel got cut off. My work around at this time is that if I manually keep the rpms up using the gas pedal it will stay running. If I take my foot off to quick it will still die but if I can do it or 20 to 40 seconds it will stay running.
Other clues:
There are no codes.
If I only drive for a shorter time, when I go to start the engine it will start but it will rev up and down (sometimes for up to ten seconds) before settling down to the proper idle.
When I start the car in the morning, it will start right up but tends to rev above 1200 rpms for about a minute or two before it will settle down.
What has been changed in the past couple of years:
IAC
MAF
EGR
Crankshaft Sensor
Wires (but not plugs)
Also the throttle body was cleaned pretty thoroughly. The guy who did it did think that the throttle body gasket was kinda iffy but intact.
I checked the FPR but no fuel leaked from it even after running the engine for five minutes.
Injectors could be going bad, maybe?? But wouldn't that cause problems other than just at a warm start?
Ford A/C :: Truck Running Cold / Heat Is Barely Warm
MY 2000 Ford F150 4.2L v6 is running cold. I bought it this summer and it ran a hair above the cold line on the temp gauge. Now that it is cooling off it doesn't come off the cold line. I have drove it for an hour and it never move. The heat is barely warm. I thought it may have been a stuck open thermostat so I changed it out with a 195 and it did not work. I can let the truck run parked for 15 minutes and still be able to grab the hose leading down to the thermo. What is wrong? The guy I bought it from used it to pull a small boat. He said it started running hot when he would pull with it so he had a new radiator, thermo and clutch fan installed. Then he said the truck ran on the colder side. Now the thing just runs plain cold!
View 1 RepliesC/K :: 454 Won't Idle - Engine Not Stay Running
I have a 1995 Chevy 2500 with a 454 engine with 72K miles. The engine won't stay running (won't idle). There is fuel spraying into the throttle body. Not sure about the pattern being correct. If I spray starting fluid into the throttle body the engine starts running fine for a short time(until the fluid is consumed). So, I'm assuming it is a fuel delivery problem. The fuel filter is O.K. Don't know about the fuel pressure.

Still showing the same codes (per repairman) and still having the intermittent rough idle at low speeds when the engine is warm. It has been so intermittent that I could almost live with it.
So repair guys first replaces the VCT's and runs fine until warmed up and the problem reoccurs with the same codes. He replaces both cam phasers and tensioners today and still same problem and same codes which point to the VCT and cam phasers.
Truck has 80k, city driven, oil changed every 3k or so. Burns ethanol and still runs great at speeds over 10 mph even when this problem appears.
Ford 7.3L Power Stroke (1999-2003) :: Flutter At Cruising Speeds And Erratic Idle
I've been having problems with hesitation and a flutter at cruising speeds as well as erratic idle. I have a 2000 F-250 SD with 497K Miles. I was having poor starts during florida winter ( had to plug in a couple times) Had no oil coming out of #2 inject and #8 buzz was weak. Flutter was there and was the original reason I started digging. Right now the only code Im throwing with my chip turned off is a P0470. I cleaned the tube and the sensor but its still throwing.
I have recently replaced all Injectors, Glow Plugs, Valve Cover Gaskets & Harnesses, CPS, Fuel Pump, ICP was replaced before new plug no oil showing.
Mods: 6637 Air Cleaner, TS-6 Chip
Truck has mad power now no problem starting. Its really starting to frustrate me Ford dealer wont troubleshoot unless I remove the chip. I feel like it should be something simple because on the throttle it will set you back in your seat cruising at 70+ no flutter ..... but slow down to 50 55 in traffic and let off the throttle when you start to ease back into it 1500 - 1800 "buck buck buck" if I monitor ICP pressure I see a fluctuation in psi of about 200 -300 psi (1400 to 1200 or 1000 to 800) . If I throttle harder it will stop or let off the throttle. I can feel it do it sometimes before the TC locks so I dont think its a TC issue. I even tested with OD off and I can recreate. The magic area appears to be 1500 - 2000 rpm....
Honda - Accord - Colorado :: Low Idle Like Going To Stall When Warm Up
I have a 99 Honda Accord, 94 K miles, received from Philadelphia last fall. When the car is cold, it idles when stopped (e.g. at a light) fine, but when it warms up, it idles so low it feels like it will stall. Also, once parked, or sometimes idling, a smell of rotten eggs comes form the exhaust. The check engine light remains on, though I replaced the gas cap. Is altitude the culprit? How to fix? It was serviced before I received it and I've changed the oil at 3 K miles once. I mostly drive low miles, locally.

My 93 Celica GT Convertible 2.2 (5s-fe?) won't stay running at idle. It starts up fine but is loping and dies unless I give it some gas. I really don't know that much about engines, but I tried disconnecting the PCV valve and the engine began to run more or less normally. I've replaced the PCV with a new one but it didn't fix the problem. The replacement PCV valve didn't seem to fit quite as tightly as the old one but that may have been due to the age of the old one. I assume there is an air flow issue of some kind, but don't know where to look next. I just want to get it running so I can sell it.

View 2 RepliesChevrolet :: 1982 - Small Block Starts Up But Will Not Stay Running Idle
I just bought a 1982 Chevy c10 305 small block.It had an oil leak so i began putting new valve cover gaskets, and then New Valve Covers(Edelbrock). Because the covers were taller, I had to remove the EGR valve and bend a new fuel line.There was a plate i installed inside the valve cover where the PVC goes into? is this a problem?I noticed the hose from the distributor rotor button(vacuum?) was not connected to anything.I plan on putting a EGR blocker plate, but was told it wasn't needed to run.
So now it starts up but will not stay running idle. Do i need an EGR blocker to run?IS that plate needed inside the Valve Cover?Does the hose from the Distributor rotor need to be connected?
Jeep - Grandcherokee :: 1996 Won't Stay Running / Codes About Idle Control And O2 Sensors
I own a 1996 Jeep Grand Cherokee Laredo V8, and there has been an ongoing problem with it stalling. The check engine light is on and it reads codes about idle control sensor and 02 sensor. I spent a lot of money having both replaced, along with an processor. I had to bring my Jeep to a dealership so they could "marry" the processor to the car. The check engine light went out for about a day, then once the computer reset, light went back on. The codes still read bad O2 and idle sensor despite them being replaced.
The problem is when the car starts cold I have to keep my foot on the gas for a couple minutes or it will stall out. Once it has warmed up the car runs good. I turned the idle pin on the front of the throttle body to try to keep from having to put my foot on the gas but it still stalls. It seems like it is working better in the cold weather. My mechanic says that I may have turned the idle too far trying to fix it and that is why it is stalling.
I just want my car to run without having to warm it up every time. It wastes time and a lot of gas. Could it be something other then what I've already replaced? I don't want to keep replacing the same things and not have it fix the problem.
Elantra XD (2001-06) :: 2005 - Slight Erratic Idle / Check Engine Light And Codes
I just purchased a 2005 elantra with 133k on it and she runs fine other than a slight erratic idle. And by slight I mean it will jump about 50-100 rpm idling and every blue moon it will jump up to 250 rpm sitting there. After idling for a while my CEL came on with the following codes.
P0507 idle air control rpm high
P0506 idle air control rpm low
P0170 fuel trim malfunction bank 1
P0121 throttle position sensor
What could be causing this? I took the iac off and cleaned it with maf cleaner but it didn't work.

View 1 RepliesHonda - Accord :: Radiator Fluid Level Low Again - Running Rough And Won't Idle?
Have a 1996 Honda Accord that had a tune up ( new plugs, wires etc). also had a leak in a radiator hose fixed. About a month later, the engine started to over heat. Fluid in radiator was very low, but no physical leak. Filled it up and in 3 days radiator is low again. This time I noticed a soft brown buildup around the radiator cap. I checked the oil filler cap to see if the underside was caramel color ( head gasket leak), but the cap was clean. Now, it is running rough and will not idle when I come to a stop. Can't figure out what is going on!
View 4 RepliesGolf IV R32 :: Erratic Shudder Occurs At Different Speeds
Well for a couple of months now I've had a really erratic shudder that occurred at different speeds and at different RPMs... I checked motor mounts, wheel balance, CV Joints, flywheel, etc. and when I took it to my mechanic, he discovered a sliced exhaust hanger in the middle of the exhaust system and nothing else.
Well after replacing this rubber hanger this vibration miraculously stopped occurring. I realized now that the movement of the exhaust which was created over certain roads with undulation caused it to flex harmonically and interrupt the workings of my Koni FSDs.
I really began to think the struts were the culprit but in the end realized the frequency from the loose exhaust was too much for the Frequency Sensing Dampers to counteract as the movements and inertia were opposite the motion of the car itself. She's now smooth as silk at highway speeds once again and only a slight vibration from the race strut bushings which were recently upgraded from stock can be felt through the steering wheel.
Prius (2001-03) :: Engine Off After Warm Up And Wandering At Interstate Speeds
Wondering if this is just my car or something that's common with the Gen 1? After my car gets warmed up, just over 150F, the first stop or coast the engine will shut off. But unless I stop again and wait the 5 seconds or so for the engine to stop, I can't get it to shut off again down a hill or coasting. I need to stop, let it shut off, then after that all is good. Lift foot, engine off. Drives me nuts when I have a long hill and it doesn't shut off! (I'm using a scan guage II to watch the rpm and water temp)
Also a question on the steering, we took a 550 mile trip this past weekend, all interstate. Although it was a little windy, the car takes constant steering input to keep it in the center of the lane. It did get old after that many miles! Common problem? I read a little on the Gen2 having problems like that but the solution was dealer adjustments. The previous owner did have a new rack put in in 2008.
