Engine + Driveline / Did we ever figure out the "Hot Start Problem"

Fixed. When I saw the solution post Thursday night, it was 2am and raining, but I grabbed a flashlight and ran out in the rain to try it. This infuriating problem has been driving me insane and keeping me from liking this car. Thank You!

Engine + Driveline / Warm start stall

« on: August 11, 2008, 09:38:30 PM »

My dad and I have been trying to figure out what the problem is with the warm rough start for a few years.  We talked to a mechanic that we get some parts from and he mentioned that a fuel injector might be leaking extra fuel into one of the cylinders and making it idle rough until the extra fuel burns off.  This seems to be good explanation for it, but we couldn't find any visual signs that one might be bad when we took it apart today.  We just ordered 4 injectors.  Hopefully this will help.  We will probably install them on Wednesday.  What do you guys think?

At least in the case of my car, I don't think a leaky injector could be the problem because the car will eventually stall if it is allowed to idle without touching the gas. One cylinder burning off extra fuel would not slowly kill the engine. Does your car stall if you let it idle after a warm start?

Hi, I am new and this is my first post. I am sort of relieved to see that I am not crazy and that other people are having the same problem. My wife drives a '91 318i sedan, and it has been doing the warm start stumble for as long as we have had it, a few years now. She loves the car and just considers the problem to be part of the cars personality, however as a dedicated car geek who does all my own work I find it to be like a rusty knife thrust into my soul. When we bought the car I replaced just about everything under the hood as far as sensors and hoses goes, and I have swapped in different coils, ECUs and AFMs and replaced the ICV and FPR in chasing the problem. Nothing has ever made a difference. The car always starts fine and drives great, until you shut it down and then attempt a warm start. Then it starts OK, but the idle will get rough and it will eventually stumble and die if you don't give it some pedal, sometimes a whole lot of pedal. You can keep it going this way, and after roughly 45 seconds it starts to run fine again until the next warm start. I eventually gave up trying to fix it and intalled a little button and a timer-relay that sends a bogus cold reading to the engine temp input to the ECU for like 30 seconds, this will help it run somewhat better until it clears up on its own. I am to the point that I am considering ripping the Motronic entirely and going MS2, but that is a lot of work on a car that is just a commutermobile and is otherwise stock. I have thought about welding in another O2 boss and temporarily putting in a wideband O2 to help figure out what is going on, I may still do this someday.
