Black smoke 1991 305 TPI
I have a 1991 Trans Am 305 TPI. Starts great, runs good, seems to hesitate at about 50 miles/hr. Check engine light comes on, black smoke out the exhuast. Try to read codes by hooking A & B pins together, check engine light just flashes, no codes. New injectors, No vacum leak, EGR seems to be working. Any suggetions would be appreciated.

Re: Black smoke 1991 305 TPI
Before you spend alot of money on parts, you may want to connect a scan tool and monitor data to see what's actually happening. Tunedperformance is correct that it may be one of those components. There are also several other possibilities, such as a wiring or power supply/grounding issue that no number of new parts will ever fix. And diagnosis by elimination gets expensive real fast.
