OK, where do I start......

First my engine light came on, which is common in any contour for many reasons.
I was getting a code telling me that there was a problem with the egr flow, so I changed the egr valve, light came back, then I changed the egr modulator, light came back, then changed the dpfe sensor, and light went out. This was quite expensive and I would suggest to start at the dpfe sensor if you come across this problem.

The problem that I am having now is the fuel economy, it is really hard on fuel, it has new plugs and wires, new air filter, and I cleaned the MAF sensor.

Any other suggestions of why this might be so hard on gas.

One question.. did you disconnect the battery and let the PCM reset after changing each part?

Take the battery out of the car for an hour. This will erase the codes that have been stored in memory. Reconect the battery and take it for a ride. Does the engine light come on?
How is the fuel economy?

removing the battery will no reset the PCM AFAIK,

the only way i know how is to clear the KAM and that is to remove the #4 and #11 (or 13? I cant remember) fuse from the fuse panel under the hood of the car. Keep them out fora about 5 min and that will reset the computer.

Oh yes, your right. But I think it's fuse 7 and 11.

just an fyi, disconnecting the battery for about 15 seconds is all it needs to clear the codes. The battery doesnt need to be removed either.
