You adjust idle with idle timing
It is controled by the computer.
turn the idle screw!
All Ford vehicles cannot adjust idle nor timing wich is pre-set at the factory and the computer sets the idle and timing, vehicles after 1990 no longer can be adjusted.
Idle on a 1985 Honda Civic is adjusted through a idle air control valve. This valve is located near the intake. Adjust the valve by either loosen or tightening it.
all depends if it's carburated or fuel injected.
timing should be set with chip disabled(curb idle)
try adjusting the ignition timing(or getting a mechanic to do it)
If your engine is ideling fast its probably temperature senser. There is no adjustment for idle. that last answer is not entirely true. u can adjust the idle. but it depends on if its a throttle body unit that looks like a carburetor or a smaller unit. on a TBI unit, there is a screw u can adjust but the only way to adjust it is with the right tool. its not a Philips screw or straight blade. but if its idling high or fast it might be the idle air control valve. the one went out on my 1985 sunbird and caused it to idle funny.
Even so eclipse uses distributor based ignition system, I'm not sure that you can adjust timing. The timing you can adjust is idle timing. But it basically never needs to be adjusted.
You don't. If you are having an issue with idling check the IAC Valve.
There is no way to adjust the idle as it is controled by the computor. You either have a idle control mod. bad or crankcase sensor. Talk to your parts store and they should be able to give you some advise also.
