horrible gas mileage on a 225
and loss of power, i get like 15 mpg and this happened recently. i vag'ed it and nothing no codes , block 32 in range. i know im running rich because i can smell it. i disconnected the maf to see if that was it but i didnt even get a check engine light, which confused me even more???? i havent check my dv but i doubt that it would lower my mpg. im running out of things to check, any suggestions?

Yes.....If fueling is not correct....>
Then you'll get a loss of power. Too rich and you'll feel a noticeable drop-off..
On these cars, all the sensors need to be working and happy for the car to run at it's best..

I changed the pre cat O2 sensor and picked up 5 mpg. at 80,000 mi.
I had no codes or CEL. Happened so gradually I was unsure if anything was wrong. I did not however have a noticable power loss.
Pointer. Get an O2 sensor socket at your autoparts store, use a 3/8 universal, a long 3/8 extension and a pull handle and you can change it without removing the charge air pipe. If you have fairly small hands. (and a high pain tolerance :-) )
