It also does this after not running for a few hours... Say during a work shift... but its not as bad as first thing in the morning.
Coolant temp sensor replaced (from Subaru)
Unplugging the intake sensor shuts the engine off so Im sure thats functioning correctly.
O2 sensor needs replacing (getting horrible gas mileage) which will be replaced this week or next week (was told Bosch universals are okay? or should I just go with Denso?)
Anything else I need to check? Thinking if I cant figure it out Ill take it to GD and have him scrutinize the engine reseal that I did.

The car in all honesty is only temporary... Next year will be a 91-94 wagon, 5 speed, AWD and be getting a frankenmotor and all the nice stuff....

Cuz I found a denso on ebay for like 55 I think... and a universal for 12....
But 38 would be good if it was a direct fit

The '90 manual trans IAC's were junk. You can try to find a used match but it will most likely be just as bad if you can find one at all. Only good fix for these is to update the computer and the IAC to a '92 - '94 units. Along with the injectors as those were also troublesome.... or perhaps buy a new IAC from the dealer but that will probably be more than the car is worth.
Upgrade the IAC? I didn't know that. I should do that. I just upgrade all my injectors to redtop and upgrade the ecu as well. Just updating the ecu was a big difference in the way my car idled. I had the same thing about in my legacy (auto though, not manual), and upgrading the ecu and the injectors solved that issue for me. Much better now.
