1G Will a 90 ISC motor work with a 91-94 TB?

[georgeh20]

just wandering if a 90 isc motor will work in a 91 because it looks like the plugs are different and the wires look different to?

will not work
90 ISC and TB are different from 91+

Will a 90 iac motor of 90 tb work on a 91-94 tb?

 

[damnslowtsi]

They are different and sit in different places on a TB so probably won't.

Alright thanks, Anyone know where I can get a good iac motor for a 91-94 tb?

Not unless you connect the wires together. On the 90's the connector comes off of the IAC. On 91-94's the IAC connects at the sensor from the wiring harness. They bolt in the same exact place.

I'm using a 90 IAC on my beater 91, works fine. Just a buncha extra wire is all.

Ya it turns out that either the 90 iac motor is bad too or there is a different problem. And if anything it is worse now. It basicaly has no control over the idle. It does not raise at all when you start it and after it is warm it idles usaly at 1500. I am also getting knock and whacky fuel trims by this. I want to buy a new iac motor but where for low money? The cheapest I've seen is $110 shipped.

Just buy a used one for like 20-40 bucks.
