Still having idle issues with my 94 gt stays above 1000-1100 base idle reset won’t do anything and I’m pretty positive I don’t have a vacuum leak pulling 21-23hg of vacuum and have smoke tested and found nothing codes on the car are KOEO 511, 12 KOER 3 and cylinder balance test is 9 thinking of just reattaching my egr to the car to see if it fixes it but I’ve also been told two different things by different people one that the egr is only active during idle and cruise and the other that the egr wouldn’t even affect the idle but I cannot find a solution to my issue
