Maybe bad injectors? Try some fuel injector cleaner.

Dirty air filter, fuel filter? I have no idea, just throwing things out there.

P0171? if so, clean your MAF sensor.

look for boost leaks .. usually people get the code for having a K&N intake typhoon mostly I believe ... but cleaning the MAF usually does the trick ... you could poss have a faulty injector! Hopefully, when you clean the filter it will go away poss too much oil around the filter? Good luck!

Thanks,
i believe the dealer cleaned out the injectors
your right it could be a bad injector.
i'll have them check them.
it has been at the dealer for a week now.
I'm not a happy camper.

You're thinking 1182, that's the intake/MAF one.


I'm surprised nobody thought of this so far for a lean code but if it's at the dealer have them check the fuel rail pressure and replace the fuel filter. Your filter could be clogged to hell and/or pump could be going out. If the rail pressure's good, then it's probably an injector or one of the harness wires.

I really really hope your car's under warranty if they're replacing all that stuff. :-)
