Hello,

I have recently installed the new Fuel filter in my car 1999 Honda Civic. Since then it seems the car is using about 30% more gas than before. I also did the tune up and the used AC compressor was installed.

I did not even used the AC after the compressor was installed.

Something I screwed up somewhere??

Thanks

What did the tune up consist of?



. Only use the exact NGK spark plugs that came in the car.
. Change the air filter.
. Change distributor cap and rotor at 60,000 miles.
. Change plug wires (provided you have 80,000 miles on the car).
