I presently purchased a 1998 Acura 2.3 CL, could you please till me where the fuel filter sets for this modal Acura car and if it would help improve the gas mileage? When I bought the car used from Acura the service department pulled the original owner service on the car record from them and it shows that they original vehicle owner had the car is up to date on the maintenance.
At present the car gets like 17-18 MPG in the city and around 20 MPG on the highway I just replaced the timing belt and put brand new tires on the vehicle hoping to see some improvement in the gas mileage.

Re: Poor Gas Mileage
Its on the fire wall yes it will help some i wouldnt expect a drastic change in fuel economy because acura dosent have a replacement schedule for fuel filters like most car companies. id check your air filter and if your check engine light is on it will seriously kill your mpg. hope this helps

try changing fuel filter and making sure tire pressure is correct keep your car clean so air can flow freely and try an oil change all these factor into good gas mileage and you could try adding new plug wires to your tune up
Is there a yellow light on the dash? Is the car very slow and struggles to rev?
It sounds to me that the ECU (car computer) is in 'limp home' mode. You need to read the ECU's code, usually by the ECU flashing lights, then look at the manual for the reason.
First up, reset the ECu by removing the negative battery lead for 30 minutes or remove the large 75AMP fuse. Run the car and see if the light returns or that it is still consuming too much gas. Then...>
One of the most common reasons for poor gas mileage on Acuras/Hondas is the O2 sensors in the exhaust manifold. These can breakdown instantly and cause rough running and poor gas mileage. There are two on the two exhaust banches. If you change one it is best to change both.
Check the air filter for dirt, clean it or buy a new one. Take the air filter housing off and run car cleaner through the intake manifold. Clean the EAVC valve which is in the intake manifold while you are there. Drive the car and take you hands off the wheel, if it pulls to one side then the brakes are seized (usually rear ones) and needs overhaul/new ones, this will cause very poor gas mileage.
Check the cheap/free stuff mentioned above first. I hope this helps and don't give up on your Acura. You have one of the best driver's cars there of the last 25 years :)....I'm very Honda biased :)
Sounds like you might have an oxygen sensor problem. Your catalytic converter(s) maybe defective or dirty. That in turn can dirty up the oxygen sensor. A defective oxygen sensor will send faulty info to the computer, interpreting the fumes as cold (even when the engine warms up). That causes the computer to adjust the fuel mixture to very rich, giving you poor gas mileage and the fuel smell. Hope it helps.
Have you changed the fuel filter? I know it sounds weird but a plugged filter will make a truck use more gas. The computer tries to compensate for less fuel by commanding the injectors to open longer. Also a plugged filter will cause excess back pressure on the fuel pump making it loud.. Good Luck.
