Hey, the camaro (88 Sport Coupe, 305 TBI) has been acting up lately, its been idling really rough, and sluggish to drive. Once the engine gets up to 2500, 3000, it just takes off. I pulled the codes from the computer, and came up with a 33 and a 45

33. High voltage (low vacuum) at mass air flow sensor (or MAP sensor

45. Oxygen sensor rich

Now I need to know exactly WHAT the problem is, now that I have the diagnosis. Any help and suggestions as to what the next step should be would be appreciated.

33. check for engine mis-fire...are all your vacuum lines connected properly? all your wires in tact and connected.

44. Lean exhaust.....check your O2 sensor....change it.

this is all the help i can give.
