I have a 1985 Z-28 305 4-bbl. H model Camaro. I am getting a engine code 23 from the ECU. My question is, I read that the code 23 is for a 'Manifold Air Temperature Sensor. As far as I can find is that my carbureted engine doesn't have that sensor -- or does it? Does anybody know what his error code may be indicating? Could it be the 'Throttle Position Indicator' on the carb? BTW, I just fixed a bad vacuum leak but the car still seems to be running lean. Also I am getting a steady vacuum reading around 18 PSI.
Thanks, AA
