Hi Arnie,

Boy, I don't wanna speak outta turn here or jump the gun, but something is wrong in Chebytown, to my way of thinking. Are you sure about that code? How sharp was the guy that was reading those codes for you?

I just don't think "Code 034" is a viable code.

The old straight OBD code of 34 would point at a MAP sensor, but that would have been in the older systems.

The newer emission evap codes should fall somewhere in the P0400 range and if indeed you are experiencing a fuel venting (dumping) type leak, it would probably be more on the order of a P0442 or a PO455, if my memory serves. If it is an actual electrical problem (like a vent solenoid) it would of course be a different code, but should still be up in that PO400 number string.

Also, just to kick this around a little, the GMs don�t have near the problems with evap systems that the Ford models do.

Maybe this young GM lad that has been dropping in on this thread can give you a better answer than I, as I am going totally by memory here; but, it sure doesn't sound right to my mind.

Hope ya get 'er going,

Allan
