I have a 92 Firebird Formula 305 V8 TPI

When I got the car I noticed that it had a hesitation when you got off the gas pedal. I checked the spark plug wires this were new as well as the spark plugs. I was looking in the forum and found out the how to look for trouble shooting coeds. The codes that I found were 45 and 22. I found the description of this code. Would the code 45 be that the oxygen sensor should be replaced or the low voltage shown on the code 22 makes that code come up?

Also If code 22 comes up were should I start to look for the problem?

Thanks

 

Code 22 describes the TPS as sticking, misadjusted, open in circut (bad conection), defective TPS, or defective ECM.
Code 45 describes both the TPS and Oxygen sensor as a possible fault.
I don't know how much you have driven the car since you've had it, but if it has been hesitating the same the whole time and not got any worse, I would guess it's the TPS. An oxygen sensor would continue to get worse over time. Unfortunatly, the TPS costs more to replace than the O sensor. Your local Auto Z should have a Haynes 82-92 firebird repair book that will locate the sensors for you.
