Re: Rough Idle
550-600rpm is normal.
Have you checked the spark plugs? You need quality one there, I don't know for that year but the 2002 ask for iridium plugs.
You said it have 190k on it, if it is still on the originals one they are long time worn out, if they are on the second set they are about gone. Mine only had 82k and the plug had to be replaced... misfire on cylinder 4... They are suposelly rated 120k...
Also, is it old fuel? it might sound stupid, but old fuel tend to have problem burning and can cause rought idle.
