I have chased this problem for a couple of weeks now.My symptoms seemed common to alot of complaints I have seen on this forum.I tried all the advice and nothing helped the problem.I finally found the cause to my problem,and if you have had your timing guide update done you might have the same problem.It is very easy to screw up the cam timing when going back together with the chain.This is what happend to the previous owner of my car.The left bank cams were pretty far out of time.If you want to see if you could have the same problem do a compression check.In my case the right bank was a consistent 175 psi,the left bank were all 125.If you have some wrench exprience this problem can be corrected without removing the valve covers.Thanks for the help I received on this forum,it sure is nice to have a smooth idling car.

fbb, yeah, the consistent uniform difference in compression test readings between the banks is a strong indication of incorrect camshaft timing on the low compression bank.

Congratulations for conquering your gremlin and thanks for posting.

How's the power now?
