At idle the engine is rough and shakes the cabin, going up to 35mpg and above is not possible. Also anytime the engine gets up to or over 2k Rpms the engine starts shaking worse!

Engine has 100k on it and has a saleen super charger, there is no smoke and am getting it towed to my mechanic asap. But what do you think?? Here are the engine codes I got off it

I was thinking that.would this cause my engine to also change temp while at idle??

I know it matches up with your DTC's and a clogged cat will make your motor choke out bad

Well cats were checked. Sparks and coils checked. Fuel pressure check, all seems fine, last resort tearing open engine to see if timing jumped /phaser are bad....should have a answer on that tomorrow or Monday

I think timing issue would have given you a timing code. My first thought were also a cat issue. However of that's been cleared sounds like you may have a bad injector, not opening. I would take a small pipe to the injectors in the bad bank to see if you can hear them cycling.

Ooo I forgot they also checked each injector and they all checked out as well. Do you think if possibly the chain jumped one tooth or something that small it would throw a timing code??

have you ever changed the plugs?
