I have a 99 Jeep Grand Cherokee Ltd 4.7L engine which I use around my dairy. I"ve recently finished the engine work (pistons, rings, bearings) and I want to smog it but before doing so, I want to solve my "check engine " light problem. Is there some way I can diagnose this myself without taking it in for $75 charge?
