'89 2.3 Check engine light code 18. Missing and bucking
My '89 will run good some of the time and then run like crap other times. It will miss and pop off the line but if you push it to the floor it will rev up like normal. I pulled the codes and got code 18 Loss of Ignition Diagnostic Monitor Signal to the control module/ spark output grounded. What might that be?
