2005 3.0 Running too lean. Any suggestions?
I have a 2005 Edge 3.0 automatic, 2WD, AC. Late last week I niticed some rough idle and decided to change the plugs but stopped short of replacing the wires. Almost for got, the truck has 62548 miles. Each plug that I pulled was white and ashy looking. I am guessing that the lean condition is causing the rough idle, but not sure what is causing it to run lean.Any suggestions as to where I can find a shop manual or something that can tell me how to test the MAF, IAC or O2 sensor? Any suggestions, hints or insight would be greatly appreciated.
