Now am I just not understanding,or is Jay Marks charging too much? If this is true,where else can one be attained?
I.S.C. valve costing $350.00?!?!?!?!

No...that's the deal, Toyota don't come cheap. Wait till you have to shell out $239 for an itty bitty knock sensor.

they dont produce these things like they used to, ya gotta understand your buying from a bucket that gets emptier as time goes by.
Toyota parts have always been expensive here and eventually you get used to paying the premium to own a Mk3!
(at first the dealer may need to use lube though)

yeah,but i'm not sure if the part is on the 7MGE and the 7MGTE are the same. Besides,before i get a chance to pick over a supra at a junk yard(sniff) they already have the motor ripped out. i have a couple of e-mails sent out to forum subscribers who are parting out cars,and hopefully i'll get a holla back
Unfortunately you have to understand that yours went bad so what says the other 18 year old car's ISC isn't bad also? If you just want peace of mind, get it new!
first you can clean it... second, if you still want it in about two weeks, you pay shipping....I'll give you one free. It works, but it needs the carbon cleaned out of it, and I don't need one anymore
ha ha ,beat you to i popped open the hood,took it out,and tested it. it was within workin peramiters. SO i took it apart and cleaned the shit out of it,ALL carbon deposits are gone,(for now) and after installing back in,it idles like new. just had a problem with the stock clamp,it leaked bad,and i just replaced it with a ideal clamp boogidy boogidy boogidy!
ISC is not cheap and there is a reason for it.
unlike every other single idle air control/idle speed control motor out there especially GM and Ford. On the 7m, stepper motor is actually an expensive piece from a manufacturing standpoint. It is a stepper motor of the unipolar design (6 pins). GM and ford use a stepper motor of the bipolar design (4 pins or 2 pins). In english unipolar means that each legs has only one way the current flows (meaning from B1 which is positive to S1-S2 and B2 to S3-S4) and the way it opens and closes the valve is by the way the sequence happens (by grounding s1-s2-s3-s4-s1.... to open and s4-s3-s2-s1-s4...... close). In a bipolar design this is not the case. In a bipolar stepper motor the legs are energized as pairs and the direction of the energy flow changes (hence the bipolar). Meaning that s1-s3 pair (s1 being postivite and s3 being negative) get energized and then the s2-s4 pair. Now what changes is that s3-s1 get enrgized but with reverse polarity (so now s3 is positive and s1 is negative). the same applies to S4-s2. BTW a unipolar stepper motor CAN be used as a bipolar stepper motor. So that is how you make the stock ICS work with a standalone like a tec3, haltech or motec
