Yea you can spray it to clean it. I was thinking how's your cam position sensor? That will also bog down your car, and make your sputter and all that.

Usually it would have weak spark. My friend had one go bad and his car wouldn't even stay running. The CPS works inconjunction with the computer to fire #1 cylinder spark.

New symptom! LoL. Ok, cleaned IAC and boy did it change the idle. It idled beautifully. But with good news must come bad. I took it on a road test because we all know that you can't truely test something in your driveway :-p

Anyway, went on a short road test because I sure as hell don't trust it yet.

I noticed that when I was slowing down that the car would stall.. First time it did it I didn't expect it, next time it did it I tried to coax it out of stalling by pressing the gas, didn't work. This is stalling when I depress the clutch to turn ( I was turning both times. )

What now?

Also, after cleaning the IAC I noticed that it really idled too high, is there a way to adjust the idle, if so where is it located? I'm idling at around 1300 rpm even after the car has fully warmed up.

Man, one down and here comes another! Yea that idle is def high, I'm not entirely sure where in that year it would be, but I assume it would be one the throttle body, My guess. Do you know if it's miss firing at all? That's so weird that it stalls when you turn. I had a car do that and there was alot of junk in the tank that would clog the fuel pump, only when I turned left though!!!..lol..sucked. Anyways, I'm gonna do some research and find out for sure for ya.

Thanks, its weird, and its not actually stalling in mid turn its just when i'm slowing down getting ready for a turn, generally after i downshift from 4th to 3rd and let the clutch out is when it stalls. and it sometimes stalls while the cluth is still depressed, either way i can give it throttle but it still stalls out. I think imma still check the fuel pressure as well because the pump was bought used. But I just don't get it.. haha.. but yea I need to get that idle lowered. I can see it idling kind of high warming up but it was at full operating temp and still idling high.
