Serious gas milage issue
Hey everyone! I'm new to the forums! I purchased a 2005 Rx8 earlier this year with a manual transmission. When I purchased the car it had a little over 20k miles on it.
Right now it has 38k miles and I've noticed that I average at about 13-14mpg... The only aftermarket part is an aem cold air intake. I drove from Duluth, Minnesota to Fairfax, Virginia a few days ago. It was 1,200 miles, and I had to stop for gas six or seven times. I had the cruise control set at between 70-80mph... Is there something seriously wrong? Thanks for your help!

I'm not complaining.. I don't mind getting 13mpg. There is a lot of worse ways to spend money. I just want to know if I should take it in for a tune up? When I bought the car I wasn't expecting to get more than 20mpg highway

Gonna do the usual recommend you to reset the PCM/ECU(I think that's what it is). This causes your car to re-learn the fuel trims. Turn your key to the ON position and go nuts on your brake pedal(20 times) - you should see the oil pressure gauge sweep up and back down to 0.
Also how are your plugs/coils/wires? Have they ever been changed?
