Hey All,
Oldtime gearhead and computer / electronics guy working on my 1994 ZR2 S10 with a 4.3 "W" motor.
I have had this truck since 2001 and over the last year rebuild most of it in an effort to keep on using it as my daily driver in the winter and my trusty tow sled for pulling my fishing boat in the summer.
I have been fighting an ongoing Check Engine light that pops on whenever the engine gets up to temp. THat is how I ended up here.
I Have an ALDL cable and I have been trying different tuner software in an effort to find some diagnostics to help me in my troubleshooting. I found a link to this board on one of the sites and I am joining in hopes of aquiring the knowledge to resolve this issue and better understand the electronic controls sytems in use on my truck.
