Is your idle RPM higher or lower than before the vibration started?
what does the engine idle at? if its below 750rpm could be your problem. should idle at 750rpm and 800rpm with headlights on.Spud said:Im not sure.I havent noticed any drop in rpm.....hhhmm....I wonder if the engine needs a tune ot something....what do you think??
Idle speed was 800 rpm....Ive never had the engine tuned.BLACK said:When last u had it tuned?? Did your mechanic check the ISC ( Idle Speed Control ) valve??
