i put a str fuil rail on stock injectors. ANd now im getting the shity 12 miles per gallon. there is like black crap all over the back of my car and its sticky and thick grease kinda stuff.

MY friend said adding a fuel rail increase something like volume, or can add more fuel. is this true could this be the reason i dont have 30 miles per gallon anymore.

Curtis.

Or could it be my tps or map or IACV.

Not the fuel rail unless you did something wrong. Probably a sensor gone. Don't ask me which one I am not to familiar with this part of a Honda.

Bump so someone can help you.

 

Do you have an adjustable FPR that you were messing with?

 

stock regulator.
I also got a new exhaust header and 2.5 all the way back with high flow cat.
and the fuel rail were all things i did at one time, then it just went to ****.

Change your O2 sensor, and check your timing.
O2 will not always throw a CEL

o2 only has original 40,000 miles on it

Curtis

 

been driving with a heavy foot lately since you have new parts?

 

do your O2, wont hurt it may be tired after 40,000 Miles, i would do it and they arnt too much money

 

my friend swears up and down, its cause put a itr header on and 2.5 exhaust all the way back with a magna flow high flow cat. But i dont think a exhaust would make a gas mileage cut in half. is that possible.

Your gas milage won't be affected my a header or an exhaust unless you broke your o2 sensor. I would just swap back to the stock fuel rail, it's not like your losing any real power right?

 

did i upgrade to bigger rims? Cos once i put my 15"s on i get 300miles. Once i put my 16"s on I get 200-240

 

I have 16's with 205 40's. fuel rail was just because it was cheap. and str, when you change exhaust could the o2 sensor go out cause the dramatic change in the exhuast flow, and how much exhaust is goin throug,

o and ive had the 16's for over a year now. never had a gas problem

 

Who did your exhaust? Is there any holes in the pipping so air can go into? I would recommend changing your o2 sensor.

 

if anything, the exhaust should have increased you mpg. I have a tenzo cat back on my si, and it gave me like 2 more mpg because of the reduced restriction.

 

thats what i was telling him. theres is no way i could believe that a better exhaust would = in you losing MPG. I think it was my timing. I will see though with the next couple tanks.

Curtis

 

why dont you advance or retard your timing if you advance it and get more spark that should accomadate? for the extra fuel you are getting

 

i don't know about u but ima change my o2 i want to get 350 miles. freakin pumping every dam week or two. KILLING ME. 25-30 bucks each time i fill up

 

i struggle to top off my car with 20 bucks in sc
how much is gas that away
its lately here been about 2.25

 

2.69 is lowest in san diego from where i stay at. O yeah its 91 because that is all i can pump

Same exact thing here

 

well just an idea, did you reset ecu after mods, to accomodate for such severe changes to exhaust, and fuel induction system?
just a thought
