Been having problems with my '99 SE Duratec 5-spd Contour for the past year or so; severe loss of power below about 4-5k RPM, and gas mileage is regularly about 19-20 MPG in town when a year and a half ago I got 24-25. Recently had the following done:

- New plugs and wires
- New fuel filter
- New air filter
- Fuel injectors cleaned

No CEL and a recent trip to Autozone confirmed no OBD-II codes were present. For about two years I had the SCA cold air intake installed, the one that puts the filter RIGHT near the road. Makes me think the problem may lie in a fouled/broken MAF, although the two wires show no sign of grunge or build-up. Maybe a bad O2 that hasn't thrown a light yet. Any suggestions?

Also, when I really get on the gas above 5-6k, my battery light will come on intermittently, then go out as soon as I drop below 5-6k. This seems to be unrelated to the gas mileage/power problem, but I'm not quite sure.

V6?

Have you checked to make sure your secondaries are opening. If they aren't the car will act sluggish below 3800 RPM.

I think you mean to make sure they're closing.
