To answer your question, the truck is running fine. It idles good, accelerates good, no knocking, etc. The only thing to suggest that something is wrong is the service light.

I found through a Google search that the 0004 code means fuel volume regulator circuit high and the 1100 means MAF intermittent. Who knows if the source is legit.

I checked the air filter yesterday and it looked pretty clean. Maybe I should change it anyway. Is there a thread or "How to" that shows how to check for vacuum leaks? I have the RAVE CD but am still getting used to navigating through it.

Thanks,
Greg

However, I CAN verify that cleaning (improperly) a Rover MAF for no reason CAN kill it, so don't bother unless it's already the problem! lol
