"88 GMC C2500 - ESC Module, issue?
My truck .. running fine, just coasting at 35mph, then , Service Engine Soon light / then ignition or ? stopped ... I thought the truck was going to die, then the light went out and truck ran fine. ( Took about 5 seconds)
The code eluded to the "just adjusted TPS".... and also the ESC ( Electronic Spark Control module).......
The ESC is interconnected to many components, like the TPS....
I am searching for a new ESC, just in case that's the problem, but anyone know of other parts that could also be connected to these parts?
I am having a difficult time finding a new ESC.......
Suggestions?
