car sputters and hesitates at wide open throttle from a dead stop. after it gets going theres no problem

How long has it been since plugs and wires were changed? These cars are somewhat sensitive to the type of wires most people say to only run ngk, but I've ran Napa lifetime wires on several of these without issues. Aside from tune up may be needing an intake cleaning, and run some injector cleaner in your gas as well.

I did plugs and wires when I bought it along with seafoam and an 3 part intake induction cleansing. got a code for tps and o2s, replaced both and everything mo'betta'. still seems to hesitate with a flucuating idle. going to clean up the iac tomorrow

swapped out my first cat with a MagnaFlow too

the throttle position sensor ended up clearing it up
