Accord :: 98 / 2.3L - Erratic Idle Speeds / Engine Can Barely Stay Running When Warm Up
98 Honda Accord with 2.3L has 354,000 miles on it and up until recently ran like it was still new. Have developed erratic idle speeds. When it is cold it idles around 1100-1200 rpm. When the radiator fans are on or the A/C compressor is on it runs around 800-900 rpm. These are normal speeds and great. However, when the engine is warm/hot, in PARK, radiator fans are off, and A/C compressor kicks off, the idle speed drops to what appears to be about a rough idling 500 rpm's and the engine can barely stay running. I've attempted to look for the obvious. I own the Honda Shop Service manual if there is a particular component or most likely suspect area I should start at.

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 9 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.
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?

The engine cranks and turns over when I turn the key, but won't stay running unless I give it some gas. My mechanic doesn't know what's wrong with it, but I haven't starting having him replace parts. What's going wrong. Could it be the fuel filter? fuel pump?
View 9 RepliesAccent LC (2000-05) :: Hard Starting / Will Not Stay Running When Engine Is Cold
My daughter has a 2000 accent , SOHC 12V, I think it's the 1.5L.. It will not stay running when the engine is cold...........after it warms up, or if it sits in the hot sun it's fine................it has 166K .
She said she took it to an auto parts store and had the engine code read, p1123 came up.....
Code P1123 : Long term fuel trim, at idle - mixture too rich..
What do you think this is caused by................ the inlet air temp sensor? I was told someone just replaced the air max flow sensor, that don't sound correct to me, but that's what they called it....probably the MAF sensor....
Suburban :: 1999 K1500 Won't Start After Rain - Engine Fire Off But Not Stay Running
'99 K1500, 5.7L, 130K miles, regularly serviced and well maintained, no garage so sits out in weather. About 8 months ago we started to experience no starts after rains, engine would fire off, but not stay running, security light NEVER came on. Took to regular mechanic and had fuel pump replaced (needed it anyway), wiring "repaired" behind dash. No problems till last month, then same started again. Sometimes will start after 5-6 tries, other times will not start till 10-12 hours AFTER rain stops.
Security light came on ONCE while driving for 5 minutes, then went out. TSB's indicate possible corrosion in the Passlock sensor voltage, underhood or under body connections, may be reason. Where these are as I would prefer to check them myself to see if simple solution before pay mechanic to find the same. Since did not reoccur for a while after fuel pump replaced, are there connections that would have to be pulled to replace tank that may now be not sealing again with time? Any resource for wiring diagrams for Passlock path?
Honda - Prelude :: 1984 - Will Only Stay Running If Engine Is Kept At 2500 RPMs Or Higher
1984 prelude...1.8l .... I have posted previously on this vehicle and I have had some "success". The car will run with the support of starting fluid but will only stay running if the engine is kept at 2500 rpms or higher. If you let off the gas, it will bog out and die. Starting it requires another shot of starting fluid and a foot on the gas.

So I did a fairly hard 1st to 2nd gear pull on my way to lunch today. Got to a stop light and I had to slam the shifter to get my car in first. Same with 2nd and reverse. Third, fourth, and fifth seem fine. With the engine off all gears select fine. With the engine running at idle, when I engage first the engine jumps. I can definitely feel it engage. I have the ecs ra4 stage 1 kit with about 40,000 miles on it. The clutch doesn't slip when driving. This seems to be the only symptom. I'm going to bleed the slave cylinder when I get fluid. Fork? Synchros? Worn pressure plate spring thingys?

I just bought a 2013 Elantra GLS last weekend. When the engine is running at idle and I'm standing outside of the car, the engine seems to be noisy. Maybe to the point where there is a small exhaust leak somewhere. I don't notice the noise when I'm driving the car - interior noise seems normal. Is it normal for the 1.8L engine to be a bit noisy at idle? The car just turned 100 miles.

Hyundai - Sonata :: 2008 - Lost Power But The Engine Kept Running At Idle
I have a 2008 Hyundai Sonata Limited w/3.3 engine with 41414 miles. I was driving along and the car lost power but the engine kept running at idle. Check engine light came on so I took it to a shop.They said the throttle control showed up bad. The whole throttle control system has to be replaced. This would cost @$450.00 Does this seem right that a car with only 41 thousand miles would need a major part like this replaced? The bumper to bumper warranty ran out in Jan 2013.
