Re: 1999 Grand Marquis Starting Problem
You rock!!!! I picked up some throttle body cleaner and MAF cleaner on my way home Tuesday. When I got home I took the MAF off and took it inside and cleaned it. The IAC was a problem, the two screws holding it on were stripped out so I did what I could to clean the throttle body and IAC. Let it all dry then put it back together. Yesterday morning it didn't want to fire up right away (it cranked 10 or 12 times) but I think there must have still be some of the throttle body cleaner gumming up the works. This morning when I fired it up it started without a problem, I didn't have to touch the gas pedal. It's idling real smoothly and seems to be back to normal. Thanks for your help!!!!
