Well I am getting closer....I am using a Auto X-ray and I am getting a code 42 Ignition timing monitor ( ican't find that problem)

I am also getting a code 34 Map too low
and code 33 map too high this was a scan from about 50mph in high gear.

How can I get both codes??

You may need to change the map sensor for those two codes. Check the wires connecting to the map sensor to see if you have a short or if the wire is bare and touching something.

 

What HAppened to the old MAP sensor?
