Just wondering if anyone has had any experience with a rough idle while in park or at a stop sign, etc. The idle doesnt hunt or anything, but the entire car will shake every couple seconds. Not a misfire or ignition related, thats already been ruled out. Hooked up NGS and ran power balance three times and each time it came back no problem, even with the tighter guidelines. Car runs fine and doesnt lack power but when its stopped it shakes noticeably every other second or so. Just hoping somone might have some ideas to chip in.
