drop in gas mileage - HELP!!

I noticed my gas mileage drop a little a few months ago and hasn't recovered. I was getting 23-25 mpg and it dropped to 20-22 mpg. I just had my 105K tune up and it dropped to 16.5 mpg!! Nothing about my driving has changed. Anyone have any words of wisdom for me???

They changed the coolant, oil, air filters and spark plugs.

did u reset ur nav mileage gauge after the tune up? i noticed that if i reset it, it takes a month of so for the average to recalculate taking into consideration how much u drive on the local and freeways.

You might get more response from sedan owners that have had the same problem if you posted in the sedan forum and not the coupe

j/k, but ouch. I feel for you, that is a HUGE drop.
