Well, I've got one more crack-pot idea, then it's to an ASE blue seal shop to get this thing fixed.
But, my oil sending unit leaks, and upon further usenet scouring, I've found out that my fuel pump is controlled by the oil sending unit. So maybe if my oil sending unit is broken it affects my car at idle because the fuel pump is getting screwy signals and leaning out my mixture?
What do you guys think... I hadn't heard of the oil sending unit doing things like this, but there seems to be some support for it. I don't knokw if it would do something so extreme as to give me like a miss at idle, but you never know.
