i just cleaned my tb and iac valve and fuel filter, after i took my secon test drive, im hearing this whining sound, i cant isolate it, anyone have a clue? it ook apart the IAC and put it back together, sprayed TB into it, its this very low whining noise, but i know it wans thtere before, any ideas?

 

Double check all the hoses and the intake assembly...make sure everything is snugged up and there are no air leaks....beyond that i have no idea

 

i sprayed TB into the IAC and everything else the TB and waht not, the noise was gone about 15 seconds i posted this thread...ironic isnt it, i retightened the IAC and cheked the ECU for codes, after that i got a check engine light, i shut the car off, turn it back on, CEL was gone, i drove around for about 15-20 minutes, no whining sound anymore and the CEL hasnt come back, i guess i dindt wipe off the excess TB cleaner?could be, another question i have is whats the screw on top of the IAC?

 

The screw is there to adjust your idle

 

thanks man, no wonder the idle seemed a little off, i thought th eTB cleaner mightve affected everything
