Message I cant seem to figure out this persisting idle issue. So during first start after car has sat all night or all day after work the idle is all over the place ranging from 1,000 all the way down to almost stalling out. It goes up and down up and down. If I try to step on the gas it will almost kill the car completely until I left off the pedal. Than sometimes after it warms up a bit and the idle settles down when I go to drive stepping on the gas will still almost stall the car out. Until car is at operating temp than it runs fine. Ive cleaned MAF, TPS, Air regulator, connectors on IACV, PTU is new, injectors are basically new, fuel filter is new, plugs are fine, ECU temp sender is new, no codes on ecu. Any ideas? ha ANY advice is greatly appreciated. Thanks all!
