1990 chevy code 42 / Running rough
I have a 1990 chevy pickup with a 305 that originally had a v6 in it, manual trans, 2wd. Its reading a code 42 that according to what I read is Electronic Spark Timing (EST) Bypass Circuit fault. I really don't know where to start with this. Is there a simple fix to this? I'm new to these new fangled computerized vehicles. Any help is appreciated.
