I have gone through the Bentley and all the individual devices on the 3.2 are in spec. I have good spark and timing with all cylinders. I have fuel injectors injecting gas. So gas and electrics are reasonably there (maybe not synchronized like they should be).

The most I can get is an occasional small backfire out the muffler. I have gone through all the docs I could find on the website and have not found symptoms like this. Anybody know of anything on the top side (like a connector or vacuum leak or plugged orifice) that I might have missed before I go back to the cams and checking all that? What is surprising me (and I am a novice) is that the vane on the intake stays closed. I would think it would open somewhat to let some air in. Helping it does nothing.

Time to go study the books some more.

thanks in advance for any reocmmendations
