    From your screen name, you have an 89 Firebird. What engine do you have? Does it have an MAF sensor, or is it speed-density?

    You really need to post all the relevant info when you post a tech question. You might want to add a "signature" containing basic info about your car, like year, model, trans, mod's etc.

      sorry i was in a hurry and just got that ? together, its a 305 TBI motor, dont know if it has a MAF sensor, i actually just bought the car and the engine light came on on the way home, checked code and its 34, not sure what it is, it doesnt seem to make the car run any diff but the light is on, and goes away after i shut it off and start it again. I'm thinkin its the cat gettin glogged but not sure. Any help would be great Thanx
