pls help</TD></TR></TABLE>are you using an OBD-I P75 ecu? Make sure all your vacuum lines are connected and that throttle body gasket is not torn. Trust me on the second part because it will cause an eratic fluctuation in idle.

 

i replace the iac and that didnt fix the problem so i am now going to look into the tb gasket

 

i replaced the t/b gasket and now i get a good idel but it is really low when it is warmed up it is idleing at 300 rpm pls help
