so what you guys are saying then is to take the wire that normally connects to the p/s pump, disconnect it, and then ground it to any part of the car INSTEAD of having it on the p/s pump? and what exactly should i look for after doing that to make sure its working correctly?

also, would you guys find it weird if i told you that right after i cleaned out all my intake hoses and then gave my throttle body a quick squirt (not a full cleaning) that now my a/c DOESNT kill the car, my lights hardly dim at idle, and the car runs a little better? because that is exactly what happened and i find it a little weird. also, i had adjusted my idle for the time being to keep it up so the car DOESNT dim, and now it pretty much brought itself back down to like 750 idle.

ok let me see if i understand......i havem y idle at 1k....if its at 1k then i have a bad isc? because the ecu should hold it at 750 at least? and my idle drops to 500 with the AC on....when i start the car the idle is not higher to warm it up....it stays where i set it at 1k....and if its cold and i try to drive it will drop to 500 then to 1k and back and forth...it will stall every now and then...when its warm its all good then.....so my guess is ICS what to u think?

id give my opinion, but im the same boat as you, so my opinion would be the most inaccurate opinion ever... lol

wire from alternator to power steering pump

Otis, you mentioned a wire the goes from the alternator harness and passes by the power steering pump... well my car has a somewhat erratic idle, it just sounds like its not healthy and it hovers between maybe 500 and 700rpm... i replaced my alternator two weeks ago and i noticed that wire youre talking about, theres a clip for it, but after having my timing belt replaced (at a shop, i dont trust me) the wire is cut off. its just sitting there, clipped in and attached to the alternator but not attached to anything on the other end... i know this cant be normal...wheres it supposed to go?? do you think this would cause the bad idle? im hoping they didnt do the timing wrong, i dont know how to diagnose that...

"and then gave my throttle body a quick squirt (not a full cleaning) that now my a/c DOESNT kill the car, my lights hardly dim at idle"

I'd say you had some deposits in your throttle body and what you did cleaned them out.

 

[BumpSkillz]

yeah thats what im thinking. in fact, it worked so well that im going to take the entire throttle body off tomorrow and clean the whole thing out. what do you guys think of reusing the gasket in the thottle body if i get them off without ruining them?

Probably old and brittle, just order one for a few bucks at a parts store to be safe.

by cleaning the throttle body are we talking about just the intake part? where th UICP connects? or like the whole throttle body? and if it is the whole throttle body is there like a walkthrough or something....i just dont want to start taking things apart and get it all fucked up ya know....thanx...im sure mine needs cleaning...i mean its 10 years old and 70k...prolly about time...thanks again

 

[BumpSkillz]

thats what im thinking... as soon as my new gaskets get here, ill take the whole throttle body out and clean it all out the right way

The factory service manual says to plug the two large ports in the bottom and then to clean the bore in the throttle plate area with carb cleaner. The two large ports connect to the FIAV and ISC, both of these could be harmed by carb cleaner. So, all you really should have to remove is the elbow.

Not satisfied with this, I removed all the sensors, switches, including the FIAV and the throttle body took a soak in carb cleaner. This is overkill but it looked nice when finished. This also gave me a chance to check out the ISC, TPS and to set the idle switch on the bench.

 

[BumpSkillz]

well if there were ever any questions about abbreviations and part function, i guess now the time to ask...

whats the FIAV?

i know what the ISC is, but whats the TPS?

id search but the threads already open and were on the subject so...

 

[barney]

FIAV = fast idle air valve - a wax pellet affair that increases idle at cold start

ISC = idle speed control - a stepper motor with plunger that maintains idle at 750 rpm

TPS = throttle position sensor - tells the ECU how far the driver has opened the thottle

Idle switch (1 gen only) = electric switch that when operated tells the ECU that the throttle is closed.
