1995 GMC C1500 V8 Two Wheel Drive Automatic
code electronic spark control module comes up but truck has no module. Changed knock sensor. Module in dist. Cleared code but comes right back
The module is new. It starts and runs, misses bad. Something is preventing the removal of the code. And. Does the knock sensor signal go straight to
the PCM when it doesn't have an electronic spark control module?
have the same problem?
