Did you guys ever fix this problem? I have it too!

I have this problem too, I just hold the gas a little when I start it up and after a couple second of holding it it will idle around 500-800 rpms. If I don't hold the gas while I start it up the engine starts and staggers to get to the right rpm but will stall out. Also starting it when its cold the engine will start and shoot to 1100-1500 rpms. My car is a 87 turbo. I want to replace the fuel filter to see if that will fix it and because it probably needs replace, I also need the check the air filter. Im pretty sure the injectors and that are okay because I had some one do the head gasket for me recently.

yeah thats exactly what mine does, hold the revs up a bit and it goes away, only does it when engine warm though maybe halfway between hot and cold marker. If you leave it to cool right down it will start no probs. Was thinking maybe it is a miss fire in engine caused by maybe silicon hoses arcing when they get warm or somthing. Im going to give it a full service and see if it goes away.

If anyone has had this problem and fixed it can you please please please tell me what it it. Thanks

I have the same problem I think it would be leaking fuel injector in the morining or when the car is cold it needs the extra fuel to start. When you get back to your car from going in its still warm it doesnt need the fuel so it floods it out causing it to run bad. Take out the dip stick and smell it if it smells like gas it is the injectors more than likely, also let it sit and idle for about 15 mins if it starts running bad and missfiring then you have the same problem I have. And I put a new gas tank filter and pump on my car 6 months ago. mabye this will help. btw I havent replaced my injectors yet.

i had a similair problem like that! it was hard to start at all times and it would die fast if i do not keep it over 1000rpm, found out that the first fuel injector gave up for some reason which i think was the cause, after getting myself new VENOM fuel injectors

it worked out great but i dont know if it this is the same problems u guys have........................
