So, things I've checked:
-Filters, screens
-ALDA
What's next? Should I check the timing chain stretch (it has never been replaced)? Should I have the injectors pop tested? I can live with low mileage but it has been getting progressively worse. The PO two owners ago (owned the car for 8 years) kept a log of mileage that I found in the glovebox. He was averaging 29 mpg at the beginning of his ownership. At the end it was averaging just 25. I'm inclined to think timing chain but that will be expensive to fix- one of the many problems with the low income high school job  .
BTW- it burns no oil |
i never saw how fast you are driving. if you drive very fast, this might be about right.
brian is getting 29 but he drives very slow. for me driving 75 on the highway i usually would get 22 or 23. if you are driving faster 21 may not be too bad. also what tires are you running? if you have very large ones and arent correcting mathematically you may actually be getting 24.
so speed is a question and as noted above checking your odo against the mile markers. i always also check my speedo against the mile markers too. sixty mph will take you one minute to go one mile.
