Just pulled the codes from my 99 contour 4 cyl 2.0 143,000 miles on it. The codes are as followed P0171 and P0102 what are these codes telling me, is it the mass air flow sensor. I just replaced the fuel filter, all 4 injectors, O2 sensor and all the plugs which look fine in color. Compression is fine in all Cylinders, but it idles rough, I'm at the point where I guess I need help with this, all help with this problem will be greatly appreciated.


Thanks, njl4

Cleaning the MAF sensor would be helpful and may solve it. Use a electronic cleaner and a swap and gently clean the sensor, let dry and re-install. A vacuum leak may also be present.
