There was a recall years back for the camshaft position sensor but 2004 should be the new type. You will need a good tech to check the spark plug voltage on each cylinder and one with a laptop to read out ALL the computer information.  Capt. George

Thank you Capt George
It sounds like you don't think it's fuel related at all?
What spark plugs do you recommend?
Also, where do I look on the engine for the year and model?
