ea82 '91 loyale 4wd 5spd TBI

 

I've looked for vacuum leaks everywhere and replaced all vacuum hose. No change. Cleaned up the IAC with BrakeKlean. No change. Checked the IAC assembly with 12V and some jumper wires. Seems to work just fine.

 

Freakin' idle is still 1300 when warm. Temp guage never climbs aboce the "C".

Also, at idle, the throttle cable is very slack. At least an inch of pedal travel before throttle is pulled back. Is this normal?

It appears that the temp sensor(s) or the thermostat are bad. If the ECU thinks the engine is still cold it will maintain fast idle.

I'm having the same problem, and I've change the thermostat. What Temp sensor do you mean?

Timming can change idle speed. Check your timming? Or is that computer controlled on SPFI EA82's?
