Unplugged IAC makes no difference....runing rich under boost. 700 1988

....and I swear to the god of your choice, I've pulled them off and checked them all, CBV included.

I know that leaks can sometomes only show up under higher pressure, so I'd like to make a schreader valve plug and test it right out.

Anyways, after a quick #1 fuse pull and an ECU reset, the car seems to pull with all the power it should, mileage is better, and no black smoke.

The last time it happened, was after a 25 min. highway trip, after getting back on to rez roads, it ran poorly. Now it's fine.

I'm going for another out of town trip tommorow night, will see what happens!

Thanks for all the advice, greatly appreciated...

Josh
