My b18a sounds like a diesel and runs rich as hell
 

Hey my integra(b18a) sounds like a diesel, runs really rich, poor gas milege, and code 42 or 43 (Im not really sure) in the ecu says "fuel system supply" is the problem.....Anybody have any ideas?

diesel?? that's a major problem... preignition most likely. I'm guessing possibly your ignition timing is way off, or you got other major problems. take this one to a pro.

So if the timing isnt off, what other problems can it be?

severe carbon buildup?

02 sensor????

Don't use diesel gas!

j/k, what ecu are you running?
any mods to fuel system?
fuel rail? fuel pump?

JSK, kill again :nods:

Maybe I should use diesel gas.....Its gonna be a turbo diesel pretty soon anyways :haha:

Its a 1992 Acura Integra with exhaust and removed bottm part of airbox, and recent external coil. It was "dieseling" b4 the external coil anyways. Everything else is stock.

By the way what else can I use to clear some of that excessive carbon build up? I already emptied an entire can of kleen flo combustion chamber cleaner and poured a bottle of Crappy tire Guaranteed to pass, and have also used a bottle of duralube fuel treatment....

it may also sound like a diesel cvar because u ahve an exhaust leak

yeah, mine sounded like a deisel with a downpipe leak
