Question about 1994 Acura Integra
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 :)
