This is an extremely odd problem i can not figure it out. At idle my car starts to rev funny, and then between 10 to 0 pounds of vacuum it backfires like crazy. I thought it was the turbo but im not sure now. The shaft in my turbo has a lot of play in it so i assumed that maybe it was hitting the housing and causing the propeelar to stop , but i guess the problem would be bigger if that was the case. So far i have changed the plugs, the injectors, wires, reset tps and mass air and nothing helps. Except for 1 thing, when i start the car if i disconnect the cam sensor everything stops. It does not backfire at all. When you disconnect the cam sensor it makes it go from sequential to bank fire. I dont know why going to bank would help this. Im so confused someone help if you would.

I would go back and make sure cam sensor is set correct.Also If timing chain is original it may be stretched and cam gear plastic broken off. That will make setting cam sensor imposible.

Well whenever i put the sensor i had it the cam reset cause we thought of that. It didnt work though.
It is getting annoying having to get out of the car and disconnect the cam sensor. cant understand why bank fire stops the problem

Still sounds like the cam sensor is mis-aligned. It's very very easy to install it out of alignment. Trust me, it can happen to the best of us

I did not understand...but if it runs better with the cam sensor unplugged...then it sounds like a cam sensor problem...either misadjusted or a bad one.

This is a shot in the dark... but have you check the coil!!! Mine backfired under boost & the occasional light throttle.

Check the ohms...

A few months back, a member of the 'other' board posted that he chased a problem similar to yours. It ended up being a broken wire coming out of the cam sensor. I don't remember what wire it was, just that it was broken along where it ran in the wiring harness.
