First, you should erase the codes and see which ones come back. That MAF code isn't the one typically seen with a faulty MAF. I'd trace the wiring and make sure that it is secure in the harness. It would also appear that the o2 sensor needs to be replaced. How's your gas mileage? I believe that the 4-4-4 is for the accellerometer; I've never heard of these causing problems or even causing a code to be thrown, but there's a first time for everything, right?

As for the 1-2-2, which socket did you pull that one from? There are two possible DTC's of 1-2-2 related to temperature.

Gas milage is about 21 MPG. I would think I could do a little better than that.

I'll reset the codes, how long do you think it'll take to re trip them if there is a problem.

I pulled the 1-2-2 from #7

I saw that 4-4-4 from #3 is no power supply to valves in hydrolic unit having - to do with the ABS. Does that sound right?

The 3-2-2 was from #1 and read that it was "Incorrect gear ratio"

Thanks
