Gas mileage was just 5.6mpg on last fill up (63.5 miles on 11.4 gallons). I usually see between 10-13mpg as my driving is all low speed with lots of stops and starts.
What could cause the sudden drop?
Two weeks ago I changed plugs (old ones looked good and were low mileage), cleaned filter (wasn't dirty) and cleaned MAF. Most of this tank was after those changes.
Car starts fine and runs fine. No engine light/codes. No visible fuel leaks. Pulled vacuum line off FRPS and no fuel or fuel smell. Oil is clean, fresh and doesn't smell like gas.
I just threw a fuel filter on it today, don't know when it was last changed but it was a FRAM so it's not original. Car has 60,000 miles. Could the filter have been the problem? Anything else I should check?
Going to do half mile drag racing Sunday and worried about this. Don't want to hurt anything.
Car has a Whipple and good/safe 93 octane dyno tune that has been on the car for the past two years.
