You can smell raw fuel when idling. Check engine light is on but I am not seeing any codes unless I just don't know how to get the codes. I replaced the fuel screen on pump. It wasn't that dirty. Any idea where MAP sensor is? Might add sparks plugs are damp. Thought I would try to check that before going to Fuel Pump. How to you clear check engine light anyways once I fix the problem?

I'm guessing to meet EPA emissions requirements. Wondering if there might be a tuner available that can adjust the fuel map. Sorry, this doesn't answer your question. I hate giving money to the dealership service department but in this case maybe you can bring it in for a proper diagnosis and then complete the work yourself.
