HOT idle failure...s
rpm wrong. hot. lots..... (less if i can SEE THAT ENGINE !)
engine not at 180F or more. 82C up.
throttle cables set wrong. up to 3 cables. must be set loose.
ECU in limphome , mode, and when so,,, cancels all idle controls now. scan it or get the flash codes.
ECU idle up pins true, (a.c on, p/s overload) and more.
on 8v engines, (ONLY) aNY AIR LEAKS,, ON 16V AIR leaks cause lean and RPM DROP, so... id love a photo of your engine..... sure would........???????
ECT reads wrong, if it read like 150F? , 1500 rpm is normal as that is cold idle speeds, dictated by THIS VALVE.
hot water not flowing trough the IAC (location not same on 8v as 16v but work the same way)
air leaks on 8v give full engine power
air leaks on 16v goes lean, and low engine power, and RPM.
so..... what engine is there, i need a photo outside usa, as inside USA it has only one 16v MPI engine. just one, but other countries, 2 engines, and 3 or more fueling systems.
more... sure, isc leaking air.
more, iac leaking air at 180F, (82C)
if rpm is 1000, then ECU is in idle up mode
there is no hot 1500 modes, ever.
does the engine flash code 12 on demand?
the DLC jumper clip?
test?
this is first and most easy.
ignore comments on NAG lamp features. it's a USA EPA bs feature.
