Title: having a hot-start issue
Post by: Eric Happy Meal on July 02, 2010, 02:03:41 AM

this has me completely stumped.  if i get the engine completely warmed up and let it sit for about 30 minutes and try to start it, it cranks over, starts, never makes it up to idle and dies.

if i start blipping the throttle it will start after a bit and drive fine after that.  car has a bunch of new OEM parts on it (from the dealer).

the car is an E30 btw

Did you read the sticky at the top of this forum page?

different issue here.

but i thought that it was going to be the idle air valve (talked with a master tech at my work) and he suggested that i get the car to where im having the problem and start cranking it over then hit the IAV and see if it starts. And when i tried it, it fired right up. so i put in a new valve last night and today i have the same problem, albeit a little less severe.

List as many of the OEM parts you can remember them installing.

I'd figure fuel pump, filter, coolant sensor, O2 sensor or maybe the AFM.  Might help to do a stomp test, though I'm sure the techs did that already.
