Hey everyone, haven't posted for a while.
I just spent $700 getting my spark plugs replaced, new oil & filter and the ticking noise in my 6G72 MIVEC fixed.
At the moment, when I am idling the car while cold it has a very serious vibration and some times I stop at traffic lights and its jumping between say 750 and 1200 rpms while idling and being really rough. While cold it's idling at 750rpm (not sure if this is lower than normal?) Anyway, it doesnt vibrate when I put it in neutral - I assume because the revvs increase to 1000rpms, and the vibration goes away almost immediately when accelerating (again, exceeding 1000rpm). It doesn't vibrate when it's finally warmed up.
Does this engine have a separate cold/warm idle speeds & if so how can I change the cold idle speed?
