Okay, so I think most of you remember the whole "my car is dead" problem.... i.e. thread
here
Okay, so long story short, the mechanic fixed everything, reset the codes... whatever that means and told me that it would take a few miles before everything worked out.
Right, so i toke it to Illinois, and living in MO, that's a far drive. The car ran smooth as silk. I drove it everyday for work during the summer and it ran smooth as silk. NOW, I'm in Rolla, I don't drive much. When I start it, it acts all crazy. It starts, it revs to 1500, tries to kill itself at 400, revs back up, the check engine light comes on and does this every time it's idling. At stoplights or in any idling situation. Pressing the gas does not help, it still idles pretty rough.
So in short, when I don't drive it a lot, it's angry at me. When I drive it, it works perfectly. WTF?????
Any help? (And don't tell me to drive it more often, I don't have time.)
