Bad Gas? Bad Fuel Pump? Bad Filter?
Bone Stock 1992 RS Camaro, 305ci, TBI, Auto Trans
60,000 miles Engine/Chassis/Drivetrain
This vehicle was parked approximately 2 years, and started yesterday on bad gas. The vehicle wouldn't idle and wouldn't run. I replaced the fuel filter and added B12 to the tank with some fresh gas. Now the vehicle idles perfectly but when the vehicle is in park/neutral it will not rev past 3000rpm at WOT, it's almost as if there is a rev limiter. You can nurse the throttle and sometimes manage to get the RPM's to redline. There is no power on the road at all.
The injectors appear to be spraying fine, air filter is not an issue, spark plugs are good, no misfire, vacuum hoses seem fine. I then reset the codes, went for a drive, and pulled the codes. These are the codes I got:
22 - MAT (Temp LO)
23 - M/C Solenoid (open or ground)
44 - Oxygen Sensor (LEAN)
Anybody want to take a stab at this one?

(EDIT: I may have caused codes 22 & 23 by removing the air cleaner)
