    Default VR Misfiring

    Hey all, my VR acclaim seems to be misfiring. Ive tested the coil, leads, spark plugs, and injectors. I cant seem to find whats wrong with it, i did a diagonstics test and codes 12 31 & 34 came up, 34 was Manifold Absolute Pressure Sensor (MAP) low voltage i wasnt really sure what this meant so i went off and tested my MAP sensor on one of my mates VRs' and it ran fine. Im not sure what to do now, if any one has any ideas it would be a big help.

    Cheers.
