hi, i have an ls2 with heads and cam and runs great. It has been tuned by many different people and the idleing problem was never able to be fixed for some reason.
The prblem is that when i start my car in the morning the idle jumps from about 400rpm to 1200 rpm but it eventually stables out (but sometimes stalls).
But if i come to a short stop in my car it will do the same thng and it usually stalls. I have the same problem when i put it in reverse going to my driveway the rpms are going up and down up and down. Same thing sometimes if i brake to go around a turn the rpms start doing that again.
But when it does idle normal it sounds really healthy and it runs perfect.
is there any advice that i can give to my tuner so he can fix this problem once and for all.!!
thank you
