The fuel filter is in the gas tank with the fuel pump - it's actually a 'SOCK' that filters fuel before it enters the pump. Odds are it's not the filter. Odds are you have a Throttle Position Sensor which is going bad (bad spots in the potentiometer). Erratic resistance changes sending BAD signals to the Engine Control Module and Transmission Control Module ECU & TCM. A good technician knows how to check it with an analog ohm meter.

It sounds like your car has a misfire.When your cars computer sets a code for a mis fire the check engine light will flash then remain on steady.The smell is most likely a rich fuel mixture because of the misfire.

2004 chevy malibu 2.2 driving 60 mph shut down


either you have a fuel pump that went out, or your fuel pump relay went. These fuel pumps last around 100,000 miles, so if you're way under that, it's more than likely the relay, if you're close to that, it could be either.
