    Hi, My truck is a 99 2wd reg 2.4 or (2rz?) my idle shifts high and low at red lights etc... mainly when the A/C is on and you can sometimes here the relays flipping out.

    things I've done
    IAC cleaned
    temp senor
    plugs wires
    new bat.

    The truck now has 307k and I got her for 750 with 296k the miles are all highway and mostly what I put on. I went over a little bit on the oil change I just did and the oil was cleaner that any motor I have ever done. SOLD on Toyota!!!!!!

    So any help? thx Jon Street

    Is your truck a manual? Does it just idle surge when putting your foot on the clutch when slowing down? If so, mine did that and I replaced the TPS and problem solved.

    its not come drive my truck....if Toyota could think for a min. a 5spd truck or car would be better with a Tech.

    My idle is not a little drop and increase its a damn spike that can sometimes cause it to die but not often:confused:

    Some stuff. Not a lot, just some.
    When's the last time the injectors were cleaner? Fuel filter changed? MAF cleaned?

    If you want to rule the AC out, just unplug the clutch.
