1996 Landcruiser idle too low

Hello all,

We had the headgasket replaced a couple of weeks ago and since then the
vehicle has not idled well at all. It will stall when driven if you
just let off the gas and even the cold (high) idle is only about 800
RPM. The dealership that replaced the headgasket (it was leaking
coolant internally) has replaced the Oxygen sensors and the catalytic
converters (didn't understand that one) in an effort to fix the idle.
All along they have claimed that the coolant being burned messed up the
Oxygen sensor (I can believe that one) and the cats. Well the engine
runs fine above idle and has plenty of power all the way up to the
redline. So I think it is an idle air control valve or something with
the computer.

Any help or advice is greatly appreciated.

TIA

Joe

P.S. I don't know why the headgasket went out and haven't heard of
anyone else having to replace one on that motor.

Maybe the throttle position sensor? Those things can be finicky....
You need to raise some stink at the dealership and make em fix it! With a
name like Toyota on the building, it should be fixed the right way. There
has to be someone there who can noodle this through.
