Need some HELP please...Car idleing weird
I posted this question a few days ago but I cant seem to resolve this problem I am having with my 99 SS M6. I changed the t-stat to a 160 and ever since then, when the car is cold and only cold, I start it and it idle goes up and down, and the temp gauge flickers. Once the car is warmed up to normal temp it's fine.
I had removed the egr and air and turned off all those codes, also turned off the codes for the 02's and changed the fan temps using ls1edit. I just re-programmed the car back to normal and its still doing it. I also changed the coolant sensor in the drivers side head. I thought this is far fetched, but I changed the tranny mount to a poly one.
Does anyone have any thoughts that could help me?? Could the computer gone bad??? The temp gauge never used to flicker up and down before the stat. I also checked all the plugs, the air box one, maf, the 2 on the throttle body. Any ideads please????? thanks

Try putting the old stat back in, then go from there. I dont know what else it could be, its not like its brain surgeory to change a stat.\
So i would be as dumbfounded as you
Good luck.

That's pretty strange... I can't see how the pcm's cold start program ONLY would be corrupted do you?
I lean toward it being a sensor or a vacuum leak or something like that... If any of your coolant sensors are fubar'd the car will run funny.
