What exactly or what part does a P0091 refer to ? It says Fuel OR Air metering ? I cleared the code with torque but it keeps coming back. I just need to know which part to buy ? Thanks !!

 

First thing to check is this:

Great thread... but it doesn't look like my wires are the problem .. at least from what I can tell. So does that mean the pump is shot ? And if so.... how much bare they ?? My car works fine now... but torque can not remove the code anymore. But yet the engine power reduced is gone and it works fine... idk what is going on...

 

Could be a bad sensor maybe? I'd have the dealership hook it up to their scanner...
