HighClass SS Posted January 19, 2014 Report Share Posted January 19, 2014 So I been a victim of the P1516 Reduce Engine Power "Bandit". So I just replaced the throttle body, unhooked battery so on and so further before removing. I hook everything back up and now my battery light is on. Any suggestions? I did clean the MAF with the right cleaner. I cleaned the t/b. Still throw the P1516. Checked all of the t/b connections best job I ever seen GM do. The t/b did have a small hole next to the TAC. Here's a pic. Aem air filter otherwise all stock. Quote Link to comment Share on other sites More sharing options...
GI.SS Posted January 19, 2014 Report Share Posted January 19, 2014 What voltage are you getting from the alternator and what voltage do you have at the battery standing still? Quote Link to comment Share on other sites More sharing options...

GI.SS Posted January 22, 2014 Report Share Posted January 22, 2014 I doubt that too. Mine were both broken and no light. I had a bad cell in the battery. Yes it was an optima. They go bad too, don't get caught up in their greatness. Quote Link to comment Share on other sites More sharing options...
