Does any one actually drive with out the ISC and if so does it do any harm etc ? as my idle revs keep changing from normal to way to high every 2nd or 3rd day then back to normal.I have a new sender in the powers steer and heat sender etc but can't afford a new ISC until payday.

Also to do with the climate conrols , i have three tubes coming out of the fire wall under the hood, 2 black , 1 green , i know where the green one goes and one of the black is also hooked up but can't for the life of me find where the other black goes which i think must control the inside out side vent as it doesnt work .Any ides ?

I dont think that it could do any major harm, dont quote me. Although it might confuse the computer.

Is it possible to increase the idle speed on an ED at all, do you know? (withough the ISC or computer bringing the rev's back down?)

The engine sounds way better idling at about 800rpm instead of 550-600rpm.

OK, you don't actually need the ISC to drive, but you MUST leave it electrically connected! remove all but one screw from the mounting bracket and swivel it out of the way, then drive. The ISC only comes in to operation on startup, to give a solid start, and if you are driving REALLY slowly, say if you were doing 5kmh up a steep driveway at half clutch or something, or parking... it keeps the engine from stalling. if you can keep your foot comfy on the gas pedal then you don't really need it.

If you disconnect the electrical connector however, the ECU wil shit itself. you won't fry it, but because it's not receiving a signal from the ISC, it will do all sorts of funny shit (well, not funny on Burwood Hwy in peak hour...

Re: Runs great with out it

Will manually changing the idle speed of your engine (via the 'little screw') fix the problem of stalling when parking etc...

Will the ECU try and correct it to the normal 600rpm by cutting the injectors out or something funky like that?
