Hey I have a 87 pickup 22re FI, when I turn it on it idles fine at around 700 to 800 rpms. after it warms up the rpms drop. It will get down to about 400 to 500 rpm idle. the truck runs fine besides that. So far i have replaced the spark plugs and wires, distributor cap, air filter, and ignition coil. I have also sprayed carb cleaner into the throttle body. Was wondering if anyone had any other ideas.

Thanks

so is the idle rough, or is the idle just low, or is it rough and low? do you have an ohm meter?

Grab a FSM (Or any manual for that matter) and follow the instructions for adjusting the idle. It sounds like somewhere down the line somebody attempted to set the idle (to the warm setting) when the motor was cold, thus, when the motor warms up, the revs drop too low.

I can scan from my haynes manual if you need it.

I thought my idle was to low .Turns out it was out of timing. Once I timed it it was fine.
