Bad fuel economy.....revisited.
I know I have started a couple threads on the issue. Here
, and here
, actually. I took in to a tranny shop to get it scanned. There were 3 trouble codes. According to Guzzle
1)P0470- Exhaust backpressure sensor circuit failure.
2)P0603- Internal Control Module KAM Error
3)P1211- ICP Not Ctrllable - Pressure Above/Desired
The tech told me that my exhaust backpressure was 24 psi at idle. We didnt get to push WOT for too long, but the short burst pushed it up to 44 psi. My torque converter seems to be locking up fine, although I'm not convinced it isn't partially to blame. I do admit it should be minimal on long trips with it locked up. He told me I probably have a clogged cat. Only problem is, I dont have one. It was removed when I installed the turbo-back MBRP exhaust. The EBP sounds high, can my tuner cause these codes to be thrown in the first place? What should I do next? Tires are at 65/85, fresh oil, re-oiled air filter, Amsoil diesel additive, fuel filter has <6000 miles....And no its not my right foot! I can drive like a grandma, and there is no change in mileage.
