I have a 06 twin turbo. Started it up after 2 years and have a check eng light on for a p1148 and a p1168. The P1148 says its something about air fuel metering. I also had one for bank1 sensor 1 heater circit low... Anyone tell me where to start with this?

 

so u bought the car with TTs?

 

If you had a shop build it they should have no problem answering this for you. You could have something simple as a dirty O2 sensor (not running for 2 years and them not getting up to operating temperature could cause a time failure). Could also be as simple as a loose intake!

 

Long block built in Texas. I built the rest. Had a shop tune it . Trying to avoid the shop cost if I can fix on my own. Just looking for someone that know more about this to give me some suggestions that's all... Thanks anyway

 

Those are for your front a/f sensors
