What the hell is wrong with my idle...it freaken idles up and down when i stop my car during a red light or sometimes it just fu*kin dies. And it always smell like **** is burning from somewhere. I have the OBD2 gsr head on the OBD1 gsr block....could that be the problem.

 

check your vacuum lines, that's the first thing to check for erratic idles

 

What mods do you have?
