IAC Overhaul?
I am asking b/c I am sick of my idle hanging around 1300 rpm
I have replaced/checked tps .98 vdc to 4.5 wot and have disassembled the IAC, cleaned the carbon out and lubricated the plunger to allow free movement with a little PB. I also have the FMS IAB manual adjustment plate and had it running/idling fine until recently. Now the RPM hangs up at idle after warmup. New 02's too so that's not it. I have cleaned the TB too to alleviate any sticky plate issues. I guess I just have to break down and get a new IAB. Anybody had anything similar? Thanks in advance...
