i have gsr engine w/ a cold air intake.. a 94-95 gsr ecu, and a catback exhaust w/ no cat.. i seriously cant get 200 miles to a full tank of gas,, w/ out beating on it and w/ out downshifting.. also highway miles suck also.. wat can i do to maybe fix this? would a vafc fix this? isnt' there an air fuel adjustment screw on the throttle body? let me no thanx...

 

Stay out of vtec and drive around 70-75, lol...

 

tune up time! fuel filter, possible o2 sensor going

 

what year and car do u have..?

 

i have a 00gsr engine, in a hatch

 

what year and model..its important..because some models have a smaller gas tank than others..so again year and model of ur hatch..?

 

92SI

 

SI has the same tank as the dx models(i'm pretty sure)..and i have the dx..yeah something is wrong..i can get over 200 easy if i stay below 4k..check ur plugs, cap, rotor, 02 sensor..basically major tune-up..

btw: i have a gsr motor too..

 

how do i go about fixing my o2 sensor??

 

get it tuned.... hondata

Do a major tuneup cause even with my H22 I get 250-270 miles on a tank so there is something wrong with your ****. Also check your timing.

 

check your timing... just a hair off and you can be loosing lots of gas. vafc can help alot but if you dont know how to tune it dont mess with it.

is your tank filling up when you get gas... might be a problem in the tank. could be dented bad or have something in it. check under the car and check the gals each time. should be around 10.2 when close to empty.
