I have a gsr, and put in 91 octane. gas here is about 2.87. On a full tank I get about 190 miles, and that’s driving conservatively. i recently changed fuel filter, spark plugs are good, o2 censor came off a 2000 integra. recently changed timing belt and tensioner, and tire pressure looks good. also poured in fuel injector clearners. none of this helped. gas is killing me and eating all my money. can someone please help. suggestions? thanks.

i also recently changed my rotors and break pads. but it does not seem like my breaks are locking, and it does not feel like i am losing power. could this led to bad gas mileage?

 

Is this a GSR swap in an 88-91 civic/crx or just an integra? What ecu are you using? What is your fuel pressure? Have you changed the distributor cap and rotor recently?

 

in an integra, gsr ecu. did not change distributor cap, and dont know what my fuel pressure is.
