1993 GMC Sierra V8 Four Wheel Drive Manual 216000 miles
My mechanic is unable to communicate with the ECM on my truck. He says the ECM could be failing but it is very rare. Would it be worthwhile to change the ECM and PROM?
Overall, the truck runs very well despite having 216, 000 miles. Thank you
have the same problem?
