lately my 97 has had some weird problems. 50% of the time it would have a sputter/miss and be a complete dog (no power) but still pulling 15-20 pounds of boost..

also when you lug it with the TC locked in 3 or OD it will have a slight bucking feel

idle wont be perfectly smooth either.

truck is bone stock besides intake and exhaust, haven't installed chip yet. not till I figure this out

no CEL, no codes, passes buzz test, contribution test, etc

I haven't check fuel psi yet. anything else I should check?

and the other 50% of the time it runs just fine.

recently did oil and all filters and cleaned screen in regulator.
