17.8 is wut i get for average mpg says the display in my 97 gt. also ive noticed when i have it on range it bounces around give or take 20 miles. somethings probly fcked up anyideas? i just put a brand new air filter in it and cleaned the plugs. i just bought it and it was sittin for a few months. it had a misfire so i cleaned all the plugs and its runing better. gotta flush fluids and sh1t but i know thats not causein it. im gonna throw some kinda gas treatment in and run it just for kicks but i wanted some input.
Don't feel bad. My GT gets the same 17.8mpg. Makes me sick cus I don't even drive it like I want to.
