my car running too rich??? crappy gas mileage and gas smell !

[sileightysomeday]

when i accelerate i can smell gas with the exhaust and i've noticed that my car is getting really crappy gas mileage. i took out the resonator and all that emissions stuff connected to the stock air box, could this have something to do with it? or is it a fuel pump problem? i think my car is running rich but i don't know why or if this is true.. anyone got suggestions? thanks.

well what do you have done first of all. Are you running a walbro, bigger injectors? Aftermarket FPR?

[sileightysomeday]

everything stock, except cone air filter.

try to see if your car has stored some trouble codes.

goto http://www.240sx.org & check out the faqs there if you don't have an online FSM yet.

Often, it's the coolant temp sensor to the ECU (not to the gauge cluster). If the ECU "sees" that it's running cold still... well it compensates by providing more fuel.

That's 1 of many variables. Here's another... 02 sensor (u can do a search on these).

there's others, but trouble code readings are a good start.

edit: well whoop-dee-doo!

then scoot over there when these suggestions didn't work out for u.

good luck!
