Running rich & very bad fuel econ issue...

[S14Chask]

im running super rich and buring up a bunch of fuel... when i get on it sometimes my car sputters and breaks up and stuff ive checked a bunch of stuff IC pipeing, set my tps to 0.45volts i have a new fuel pump but not yet have installed it.. any ideas what it could be??? this is my 2nd sr20 my first one never acted like this.. but idk.. also when im drifting if i go right i have no issues but when i slide left it has like no power its stupid and annoying.

Have you checked your mafs? I'd do a volt test on it. While running. If it checks out volt wise it doesn't mean it is good. Tap the mafs with a screw driver when doing the volt test and if the volts jump when you tap it then that means the solder inside has broken contact. Its an easy fix. Just resolder the three connections. As far as your power loss while drifting, do you have an open end diff? If so that's why.

Are you running stock boost? Are you currently using the stock fuel pump? If so Since its a track car just weld the diff or get a j30 lsd...Did you check your TPS voltage at WOT?You might want to double check your timing.What fuel filter are you running and how old is it?

check your timing and your injectors
