Man O man,

I've had the car problem from hades! I've no codes, but found something interesting. My map sensor is reading 4.76 @ idle, or Key on engine off. When I start my car, it runs as if it only has 4 cylinders! NO codes, right. Now, I have a 2 bar map sensor that belongs to my timing retard for my supercharger. I take it off my crane box and i put it on the stock harness and I get 2.33volts at idle or koeoff. My car actaully idles a bit better, not a whole lot, but it atleast runs. I get a code 33 after I use that map sensor.

What is the voltage supposed to be for idle and wot at the map sensor. I thought it was around 1.5 for idle and 5v for wot.

Thank you!!!
