Hey all,
In my newest battle with my cars idle (too fast... which i thought id sorted) i fitted up a new TB which i cleaned up nicely which also had a new TPS with it.
After cleaning up my IAC and whacking it in the TB i adjusted the butterfly so that i couldnt see any light around the edges (figured thatd help prevent fast idle and i could just crank it open till car idled at a decent pace).
After I fitted all of it to the car i kicked the car over and i could here this massive sucking noise and the car was still revving too high, had a look no air leaking aroud the butterfly or at least the butterfly hadnt been sucked open. So i stuck my finger over the port for the IAC valve and the car stalled (thank god no other massive vacuum leaks :thumbsup: ) also the sucking was all happening from the IAC port.
So if all the air is being sucked in through the IAC port and the car is still idling too fast does this mean my IAC valve is too pussy to close up properly??? (it does work to some degree, just as the car seems to be approaching a decent low idle speed it runs out off action, i can use my finger to do the job sliding it over the IAC port closing it off bit by bit and i can get a nice low idle).
So just to make it short and sweet now....
Finger over IAC port car stalls
finger partially over IAC port idle control
IAC valve doin its business car idles high
Time for new IAC valve???
Cheers, Apoc.
