is it possible to replace the ground without removing the UIM and LIM?

 

Yeah forget it exists and run a new one from a tranny bolt to the frame of the car.

 

the series 4 pressure sensor have a screw on the shock tower to adjust the rich/lean but from my experience... the pressure sensor is bad.. if u pluck it.. and it starts idling like crap or bouncy .. then it definetly is messed up.. just change it with a different one.. and u'll see the difference

 

thanks everyone...I'll be sure to let you know how it turns out.
