The ECU *learns* how to idle, so if it idles fast after a restart, you might want to try disconnecting the battery for 10-20 minutes. This will reset the ECU (to factory/ default settings). If its still under warranty, I'd just take it back to Ford and let them deal w/ it.

Since you get such a good deal on Ford prods from your brother, it may be advisable to also get an extended warranty with a portion of the money you save.

Cpayne you seem to know alot about autos do you know much about ac systems. Mine blows cold at idle but blows warm when I'm driving. I have to run on max AC fro it to blow any cold air. I had it looked at and at first they said I had a vacume leak then they said my compressor was weak. I thought that was weard because of how it blows cold at idle. I don't mind paying to have it replaced but I would hate to spend $800.00 and that not be problem. Thank for any info. Its a 1998 ford Explorer
