Re: (ToTheTop)

i just did a basic scan and it didnt pull up any codes, I was going to start tomorrow with block 016 which i believe is the misfire counter, ive done it before just cant remember which two blocks to use

I would lean towards a vacuum leak...does your boost gauge show hg? It should be at 20 during idle.
Recheck all vacuum lines. Make sure to check lines under intake manifold. I've had similar issues and it turned out to be a hose under manifold that popped off.
