I need to know what the compression should be in a 12a? My front rotor is running lower compression then the rear rotor. My car will idle and run, but when I put it in drive it shuts off. Help me get my baby running. thanks

 

I dont think that has anything to do with your rotors, front or back. Check vaccum lines. I take it this car is automatic....dont know much about'em sorry couldnt be more helpful.

 

any bit helps, yes it is an automatic

 

Well....If the car stays on and revs strong up in "PARK" then its not the motor. Again try checking vacuum lines 1st.
