B20 Vtec Turbo - Running lean after warm up? Why?
Posted: Sat Aug 06, 2011 5:06 am
As titled say's, my engine is running lean after it warms up. It's driving me crazy and I'm having trouble locating the problem. Anyone have any idea's??
I can Start the car and it starts perfect, Idles perfect, AF read's perfect, until about the temp 170-177, then it starts to idle alittle rough and AF's jump back and forth from 16 through --, why is this? I haven't driven the car because I'm scared of messing something up running it lean like that, so I don't know AF at WOT. I know when it's idling lean, I can give it gas and the fuel comes back and AF reads fine, once the rpm's come back down, straight back to lean....wth?
EDIT... I'm running the hondata s300 and the only tune I have is one a tuner gave me that was a dyno tune for a engine like mine, expect different size injector's. So if one of you know's alot about the Smanager, is there a place in there that I can up the fuel on idle after warm up??
