Unfortunately I had already had ordered a used one from performance partout, it was only $30 shipped. So I guess it's worth the gamble. I had replaced my isc once already, back in 2017. If I remember correctly it was a standard brand, not sure why it failed so fast. I did take it apart, and inspected it. Can't really see anything of concern, and I can manually turn the plunger in and out. I'm really hoping the issue isn't in my engine harness. I've had several points of failure that haven't made much sense. I think maybe the harness got damaged somewhere, and I can't find it without a major job of pulling it out. And unwrapping. So I might do an ohm test on all of the wires to the ISC. From the ECU to the harness plug. My question is I see there are 4 ISC wires coming from the ECU, but 6 at the plug. Are the other two just sensor grounds?AEM is annoying sometimes.
When my ISC went bad it still tested fine in the Ohm test, just like what you are saying.
I would not waste my time buying a used one. Get a new one while they are still available, and before the new prices go any higher.
Right now from Rock Auto you can get a new one for:
$69.79 (Standard Motor Products AC146)
or
$157.99 (WVE/AIRTEX/WELLS 2H1098)
I am using the Standard Motor Products AC146 in my car and it is good. When I bought mine the Airtex/Wells was only about $70 but their price has gone wacko since then.
The drill-down in Rockauto goes like this: Eagle, 1991, Talon, Turbo, Fuel and Air, Idle Air Control Valve.
Here's a link that should take you right there.
