Engine Performance problem
2005 Pontiac Grand Am 6 cyl Front Wheel Drive Automatic 109812 miles
ok we have changed the plug, wires, front oxygen sensor, cleaned the mass air flow sensor and changed the fuel filter twice and still over the last year my car keeps getting worse with missing when going under 40mph also had issues wanting to start on first try. At times when I turn it on to warm up I get into it and smell gas inside the car. Its eating through gas now and the missing is getting worse. I used to get like 320 to a tank now I get like 240. We are lost, I have been told it could be the fuel regulator or the cadillac converter. Please help befor it nickle and dimes me playig the guessing game.
