nope no CEL only when i unplug that sensor, not sure how old the O2 sensor is but it was on the car when i bought it, same witht he spark plugs, and its got the right ECU...right now its got a VAFC in it and i know its running a lil rich but it never seemed to have this low gas mileage before so iono

 

I know I'm saying the simple stuff, but I like to start with that first... last time you cleaned your injectors with a service, last time you changed the oil?

 

you unplugged your throttle positioning sensor "TPS" . also on ur vafc is your fuel on the low end turned down alot? what ecu are you running?

 

just change the oil not too long ago, nvr cleaned the injectors...ive had this car since last summer and working on it and troubleshooting it since then is basically the experience i have...i know im a noob

 

ummm i have no idea, the most ive done with that thing is change what info shows up on the screen, so i have no idea
im guessing stock gsr ECU...i bought it with the swap in it

 

How many miles are on your fuel filter. If you replace it ONLY use a honda one. Air pressure, radiator mixture, spark plugs, a lot can affect your mileage. I had a built all-motor set up with 330rc injectors (tuned) that got the same mileage as you. You should be getting more like 30mpg.

 

Change your Plugs and Wires, and Then clean the IACV with Carb Cleaner and Dry out for 20 mins. then your good to go.

 

cleaned the IACV and checked the plugs and wires they are good so hopefully this will do the trick with the idle problem, ill let yall know as soon as i find out how it drives

 

i would take the vafc out if your not gonna use it to tune... i have a motor with internals/ cams/pistons/tuned and i get 30mpg street and about 36mpg highway... vafc could be messing with your ecu's readings...
