Since I bought my car 9/ 2001 my mpg has been within 1 mpg =/- of 22.5 around town or long highway run, all of a sudden I'm getting 17-18.
The only thing I have recently done to the car is put on a 90,000 mile used AFM while chasing the stumbling idle problem, could the AFM be the culprit?
Also the MPG drop was sudden not gradual.
TIA
I did have a failed alignment attempt that left me with a decent pull to the left that I haven't had a chance to correct yet but a scrubbing tire could'nt have that much drag could it?

The AFM probably needs adjustment. I had one replaced on mine with a used one from my friend's shop and we were there for about an hour trying to adjust it.
Have you replaced the O2 sensor on your car also and did a cap and rotor???

You need to sell that thing to me and get a 951... ![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
I'm also having gas mileage issues. My overdue tune-up is really starting to show.. I was getting a solid 26MPG, now it's down to 20 or so.
Could it also be the lousy blend of premium gas they are pushing on us?
