Hey guys, it looks like I may have a Vacuum leak, any ideas on where to start? ERG is recently replaced, I was also getting a misfire on one, due to spark plug, I replaced that myself sunday. But I am still getting a shudder, or heavy vibrations at a stop while the AC is on. When I did the report, the ERG was showing up again, but the Autozone guy said they probably did not reset the computer. Should I reset the computer and get another reading. If so, how do I do that?

Unhook the battery for 15 min, then check again. As far as vaccuum leak, you just gotta go with the calibrated eye.. there are tricks guys use like spraying certain fluids over areas and seeing if the idle fluctuates or anything, but try that out first
