thanks alot, poolgod27ia

I had the same thing awhile back, It is in your computer.I had a pivot switch put in my car and the mechanic screwed up some wires in my steering column, i bought a computer before i had them fix the wires, so i wasted my money on the computer. But the quad drivers are in your computer. If your looking for one i have a spare that i would sell. All you would have to do is take your chip out of yours and place it in the new computer.

Good luck,

Use the search function.....There'* about 400 topics of QDM failures in the forums here.....

A qdm failure can usually be summarized as the computer does not see the voltage level it expects on something. This could be caused my bad item, ground issue, broken wires...tons of stuff. And then there'* the old standby, the computer could have gone bad.

How'* your boost level? How your voltage? Check the EVAP Canister Purge Solenoid?

thanks to you all for the replys i'm going to try the comp first cause i did at one time had 12 wires so i fix them all and the camshaft sesor still pops up so i'm going to run new wires to the ciol pack and comp mod then put the thrid new sensor in and try the other comp and see what happen once again thanks for all your help and i'll let you know what happens in a bit.
