I just bought a 1990 firebird 3.1L v6. Even though the SEL light wasn't on it had horrible acceleration even after a full tune up (plugs, wires, filters, timing, fuel filter, and welding up holes the previous owner put in the exhaust pipe to make the car sound cooler). The car runs at normal temp, but smells ric, and has major power lag, especially when going up any incline. Yesterday I had autozone check the codes and it had a code 22, I bought the new TPS and installed it right there in the parking lot. Now the SEL light is on al the time and the code it is throwing is the same code 22. The accelleration is slightly better, but not much. I thought maybe the tps was bad and exchanged it for another with the same result. Any help getting this car in working order would be greatly appreciated.
