I just changed the timing chain. And the old one was about an 1/4"longer and a littebit loose but not real bad. But it still backfires the same.

I also checked the valve train. Set the rocker and all the valves have full range of motion and none of them were sticking or binding.

So i guess im down to replacing sensors. Or the fuel injectors. Has anyone had issues with the injectors sticking open? That would explain the backfire in the exaust, the lost of power and the 6 miles to the gallon.
