I replaced my head gaskets on my 95 firebird 3.4l. Now when i start the car up it jumps up to 4000 rpms. i made sure all the electrical connections were correct and i played with the tps,iac and the o2 sensors and nothing changed. there isnt many vacuum lines on the car and ive checked those too. i was wondering if on this model there is a groud strap located on the cylinder head towards the rear of the motor or if anyone knows why this is happening? thanks
