I have a 94 C1500 Suburban with a 5.7L TBI engine. I have been having issues with the engine randomly searching for idle when I stop at a traffic light. It doesn't happen all the time but does seem to be worse when it is hot. I have already rebuilt the throttle body and checked for vacuum leaks, and the spark plugs look okay. The voltage gauge also seems to fluctuate with the idle when it does it. I suspect this is due to the changing rpm, but not sure which came first, the voltage drop or the engine idle? I am looking for the next steps to troubleshoot this issue. Any ideas?
Thanks for the help
