2001 Saturn L series 4 cyl sedan 170K miles. New plugs and air filter. Put on cmptr. No error codes. Problem is dropping mileage. 100 miles per tank? Used to get over 30mpg @ 70mph. Now barely 26 at 60mph? Catylitic converter seems good and no error codes? No offensive smell and car seems to have all it's power. FYI.I'm not a leadfoot. Any ideas?

I would check your tire pressures it could just be the blend of gas your getting they keep changing it and not for the better.I have seen sometimes the mileage just change from one season to the next and they change the gas blend different season. If your car was running too rich the computer usually picks it up and sets a code.
