1992 civic bad gas mileage please help
my girlfriends car is getting less then 20 mpg. i have already changed the plugs, wires, cap rotor and pcv valve. the only thing i havent changed is the fuel filter. i have no check engine light and the car seems to run fine, but runs rich by the smell coming from the exhaust. also sometimes after i get out of the car i can smell unburned gas. please help what can it be???

i just havent got around to changing the fuel filter, the check engine light works and is not on. i dont see any leaks but havent checked and not to sure how to check for leaks. the exhaust sounds fine and dont think there is any leaks. the 02 sensor has been changed and the distribitor has been changed and set to timing.

Timing set with a timing gun?
Inspect the spark plugs. Post pictures.
Does the engine run cold as seen on the temp gauge in the cluster?
Automatic transmission?
Driving style?
A/C used?
City versus highway driving?

An automatic transmission Civic driven all city miles with the A/C on won't get great gas mileage. You might not be very far off from normal.
How long does it take the cold engine to fully warm up?

We'd make much faster progress when you decide it's important to provide answers to all questions. Otherwise, this is just a chat thread rather than a productive technical thread.
