Re: How to clear codes
The manual that I got says it sould be 34-36psi idle to full rpm. That just doesn't seem correct. And if it is what could be my problem. Could a plugged up gas tank vent cause that, because I had problem with bee's and noticed some hanging around that area.

Re: How to clear codes
I followed the flow chart that I have for that code. I checked the 5v ref. and ground all the way back to the ecm. So the wiring checked out on all 3 wires. From what the flow chart is saying, replace the map sensor. That why I wanted if maybe I happen to put in the wrong map sensor with the wrong values.

Re: How to clear codes
I had code 33 and followed that same procedure. It said replace MAP sensor. So I did and the code is gone. But I am not sure what was wrong. The engine runs OK but so it did while throwing the code too. ?? BTW I changed to an automotive GM style MAP sensor, it was about half the price.
