I have a 89 formula with a tbi 305. lately it have been acting up, every once in a while it will stutter going down the road and then the service engine light comes on and it wont run with near the power it usually has. it usually happends going down an on ramp, or when the throttle is opened up over half way. then once the car is shut off it resets and everythings fine till the next time it happends. i was thinking it had something to do with the throttle positioning sensor, but if anyone had any other ideas im all ears.....
thanks
