Running lean??

Raksj04 · 01-26-2012, 04:29 PM

I have a little update. The car seems to be a little lean under boost but will start to come back down. AT curise around 20in/hg of vaccum the acts like my bike does when I need to switch to the lower part of the fuel tank. And the AFR are pretty erractic at this point. If the rpms are about 2k to about 4k. To me it seems like its not getting enough fuel at this point, I am not sure why. Under slight accel the AFR are richer about 13 or so. I know in the Mazda FSM there is a tool that is used to check fuel pressure of the pump and the FPR. It is basiclly a gauge with a ball vavle on it. Does anyone know where I can get one or how to make one?
