Do a forum search on this subject.

i found this black stuff like a graphite or plastic not sure exactly in this one rubber line coming from my air pump...is that bad?...and the other rubber fitting goin into my engine was split so i removed it,is that also bad? I don't know this one, but I would think that you should replace any defective hose that is split or cracked.

i also have a surging idle so i unplugged my IAC...whats the cheaper routes to fixing a high idle? cuz now i have rough starts due to my IAC being unplugged
Try removing your Idle Control Valve and give it a good cleaning and check the operation with test voltage. Check your OVP relay. Again, do a forum search on this subject.
my wiper comes on every once and a while on its own..i noticed that if the handle is turned backwards it makes it come on..do i have a bad connection? do i need a new handle? Not sure???

my auxilary fans NEVER come on..even when the temp climbs and when i have the AC on...and i know they work cuz i tested them by runnin a wire from my batt to them..so whats bad some type or sensor? Start by checking the aux. fan fuse first, then the aux. fan relay, then the aux. fan temp. sensor. I start with the temp. sensor because when I short out the connector I can hear the aux. fan relay operate first, then the aux. fan comes on, that way I know the circuit is OK.

i got lots mroe questions i just need to remember them all. Write everything down and keep a record of your problems and things you have checked, replaced, or fixed.
