here is my problem: when i start my car for the first time during the day it runs fine, no problems at all. air/fuel ratio is good runs and drives fine....probably after a good 30mins of driving the car, it wants to run lean at idle, like 16-17 a/f....and when im coming to a stop, sometimes it will cut off and i gotta crank it back on....now i talked to a friend and he says it sounds like the fuel pump...i have a walbro 255, maybe its gone bad? if anyone could chime in on this and help me out, would be much appreciated...oh and the car was tuned from a respectable tuner about 2 months ago and made 344whp and 300wtq....
THANKS!

Re: NEED A LITTLE RB25 HELP!
well i just went through this with my sr20. my coolant was low so when it warmed up it was running lean. i fixed the leak and topped it off and problem solved. have you checked fuel pressure? also this problem didnt start happening till it got cold...im thinking about turning up the fuel pressure a little bit.
