So Sunday bought a 96 4 door civic with only 125k on it. It’s only the 2nd 4cyl I’ve ever owned and it’s dog asssss slow. Automatic...runs like a sewing machine but I think the motor is a little tired bc the reason I think I’m not getting good gas mpg is bc this thing is so slow I have to hammer it to get up hills, merge onto the highway, pass slow drivers. Anything I should do without turning it into a tuner rice mobile!!? Intake, hypertec, sell it and get a accord?.
