Warm Start Issues

[Griffster]

Hi All,

On my Griff 500, when I have a normally hot engine, stop the car, turn it off. If I then go back to it 10 - 30 minutes later or so it idles quite roughly, revs dip up and down and on one occasion it has stalled. This might last 10 or 15 seconds then it rights itself.

Can anyone tell me what is wrong?

Cheers

Simon

Id take a stab at the fueling not being quite correct when it restarts, and the ECU does not correct the mixture until the lambda probes get hot enough to give a reading (this is your time delay). Its possible one of the temp sensors is not giving the correct output, leading to the wrong fueling in the first place.
