hey i have a 92 slc and it idles at about 500 sometimes.. (basically after its warm but im not sure exactly why it does it [like if its hot or something]) i was looking around on the CCA website and they were talking about a rough idle problem but for them it was the idle was too high. uh does anyone have any ideas on what could be the issue? thanks

TTT
huh

try cleaning the ISV... if you are also having problems with it bogging down and almost dying, it could be the coil pack going out.

i was thinking o2 sensor? where is the coilpack and how do i tell if it has gone bad?
