1. my idle acts the exact opposite of what its suppose to do. when the car is cold, the idle is low, hovering around 800. at this point, the car acts like it wants to die and most of the time it does unless i rev it up to about 1500 for about a minute or two. then when it warms up, it hovers around 1500. it doesnt stay put at a specific number when its cold or warm. its not exactly surging, but itll kinda bounce around within about 100-200 rpms. 2. my alternator pulley squeels like a bitch. it does it off and on. sometimes it will, sometimes it wont. the only time its guaranteed to do it is when i add some electrical load i.e. the lights. most of the time, i just have to rev up the engine to about 3 or 4k and itll stop for the moment. it really only does it at lower rpms. no codes or anything.. anyone have any ideas?
