Re: Rough Idle, "01 Navigator
Ok people, first off thanks for the help. The problem became less intermittent, and now it think it's completely gone. I'm waiting for more time to pass to be sure, will keep checking for codes.
This is what I've done. I bought some spark plugs and changed out the four on the passenger side. The third and fouth ones had had a bit of oil on them. That worried me, but I read that that may happen if too much oil is added on an oil change. I had my oil changed at walmart last, it doesn't suprise me that they'd over fill while rushing.
I then bought a cleaner for the IAC valve, which is the same cleaner for the throttle body, and cleaned out the valve and the throttle body. After putting things back together, things have been feeling, sounding, running great.
I still need to change out the other four spark plugs on the driver side, and hope not to find oil on any of them. I am also going to do an oil change myself.
This may sound dumb, but why is it that even though my engine calls for 5w-20, because of it having alot of miles, people suggest an oil thats 5w-30/40/50?
