man i smell like gas.i just got done driving in my 91 crx si with a b16A swap...2.25 pipes from the man back (no cat )..i am getting like 10 miles to a gallon...waht can be the problem?

 

There are so many things that could be wrong, you have to describe your problem better.

I'm kind of confused by the way you phrased your question.

 

if you were to ride in the car with me you would smell like gas fumes afterwards...also my gas milage SUCKS...i just went about 60-70 miles and used a half tank

 

do you smell it especially in the cabin, or also in the engine bay?

do you see gas anywhere, can you smell where it's concentrated... does it happen only on WOT, or just driving around

 

just when i drive around......if i have been driving about 30 mins you can smell my car if you were outside when i pulled up

 

those u lines, that go from the tank to the lines, that metal line is notorious for
rusting, or fitting leaking, check her out

 

turn on the car to pressurize the fuel system and look in the engine bay to make sure no fuel is spraying. if not then pull up the back seat and take off the metal cap behind the seat. in there you will be able to look at the connections at the tank and the filler neck, to see if any of them are leaking. if you smell it strong in the cabin then i would suspect it to be in here. lastly, there is a plastic cover behind the drivers rear wheel, this also has three fuel hose connection that could be faulty.

 

any other ideas out there...thanks a lot for all of the help......

 

now i am throwing my map sensor code and one of my vtec codes i think...22?

 

would the code five MAYBE be the reason for the gas smell? or bad gas milage?

hmmm not sure.. but if you want to know the actual milage your getting. full tank your car. reset your trip odomiter or keep track your milage.. now use it for about till your in E. gas up your car.. millage devide that to gallons of how much youve just put it.= mpg. i get about 25 mpg.. not bad. considiring when my gas tank is on E and i full tank that sucker. its max out on 7 gl only..

my car can only take 7 gl too, its weird cuz i have an 11.9 gl tank. i was thinking my guage is off alot but i dont want ot test it and run out of gas

 

What you can do is bring a spare container of gas with you so you can run out with a clean mind.

 

What type and grade of gas do you fill up with?

 

i assume one of your injector might be bad?

oh good. i thought i was the only one that had that problem.

 

i use shell V-power mostly......so i should check under the hood for spraying, then check the other lines...?

 

your definatley leaking fuel, id follow the hose coming off of your fuel filter going into the fuel rail , make sure all that stuff is tight, if its not that then check the fuel return line coming off the rail going into the firewall on the driver side, i had a similar problem and it wouldnt leak under idle but once i gave it gas it would leak.

 

i looked in the engine bay.......i let the engine get warm and all...then i pulled the throttle cable and looked for any spraying...i COULD NOT find anything...where else do i need to look or am i just missing something here

 

u shouldnt floor your car all over town....higher rpms = shitty gas mileage...

 

it might not spray, in my case it was dripping, check around the fpr, check the right side of the fuel rail where the fuel return goes, check the line coming off the fuel filter going into the fuel rail.

how old is your fuel filter

 

also your o2 sensor might be going bad.

 

are you sure it's fresh gas, or is it exhaust fumes?
maybe you're running rich. a faulty map sensor will probably screw with your A/f ratio and thus mess with your gas mileage.

 

i looked everywhere for a leak...i found none!!!!!! i think maybe i have a bad ECU..or something else.....iu am throwing code 5(map)...but would that cause me to get like 80 miles per TANK
