Bad Gas Mileage after 90,000 mile svc and timing belt ???

[mooneybeams]

I have a 99 Accord LX with 106,000 miles on it. I got my 90,000 mile service and timing belt replaced at 100,000 miles. I used to get between 420-440 miles on one tank. Ever since the service I only get 360 or so. Anybody got any ideas? I took it to the dealer and they couldn't find anything. They reset my computer and said that would fix it and it has not...

maybe they set the timing wrong. i've seen dealers that are not doing a good job on valve adjustaments and the car keeps on butning more gas.

and that's a lot of miles for a 99 :paranoid: :eek:
