Ha!!! Stupid Isc

wELL i PULLED OFF THE uim TODAY AND TO NO SURPRISE MY isc WAS STUCK OPEN! Woops caps.So I will simply clog it up with something and get block off plates later on and hope it doesn't bother me again. Are there an side effects when taking the ISC off? I did a search didnt find much at all. I mean it stabilitates idel but other then that is there any side effect?

From page F-81 of the FSM (you can tell it's authentic by the bad grammar):

Quote:

Idle speed control (ISC) system controls the bypass air amount that passes through the throttle valve, the idle-speed control system performs feedback control so that engine idle smoothly and at target speed. The system also performs the function of the AAV (Anti-afterburns valve), there by eliminating the AAV and simplifying deceleration control system.

This ISC is operated by a signal from the ECU. It's supposed to maintain 700-800rpm, and 1000rpm under electrical load or when the A/C is on. It's also responsible for the infamous "idle bouncing". Getting rid of the ISC and AWS will let you manually control your idle, but it will lower if you pull up on the gas pedal (if you haven't recently changed your throttle cable) or turn on all the gadgets inside the car.

What do you mean it will lower if i pull on the gas?

Pull the accelerator pedal towards you. I can do it on my car it takes a few minutes for the ECU to compensate and raise the idle back to where it should be.

just make sure your throttle cable isnt overly tight and you shouldnt have to worry about that.
