Keep having p219a show up. Bank 1 air/fuel ratio Then goes away for a few weeks then comes back. Can reset with disconnecting battery.
dealer says needs new injectors and fuel rail. But everything they tested was good.
curious if anyone else has these issues?
This unit has been a nightmare. New trans axle, new cooler, new battery, replaced a bunch of air related items at the dealer as well.
curently have 104,000 Km on it.
many help would be great without having to spend thousands more on it.

 

I'd run a fuel injector cleaner with PEA. Techron and Lucas both have PEA. I've heard Gumout has it now, but don't know. Sounds like dirty injectors to me.
