lots of gas

[kevin]

my 87 supra seems to be running very rich.when the car is running i can smell the gas in the exahust,and when i get on it it smokes a little and it smells like gas what are some things i can do to lean it out?

is one of your plugs fouled? wires bad? maybe you need a tuneup to use that gas instead of pumping it out into the air?

maybe you have a boost leak(ait leak after turbo) this means air is escaping that your afm has measured and added gas for.

is your fuel pump or fuel filter acting up?
my guess it is one of the first 2 things.


in any event, ways to alter fuel map are:

the apexi super afc can lean out an engine electronically.

the lexus afm off an sc400(v-8) adds 25% more air, which would lean out your engine. that might be a bad thing in my opinion.

some guysrun a hose from between the afm and air filter to between the afm and turbo. this lets in an amount of air that will be unmetered, which in effect leans out your engine.

WARNING!!! without knowing why you get extra gas out the tailpipe, leaning out the engine could be very bad. WARNING!!
