Re: running lean
you must not understand how that kind of a/f ratio gauge works. its a narrowband gauge. when you are NOT in WOT situations, the gauge is useless b/c the ECU is constantly going from lean to rich to keep a 14.7:1 a/f ratio. so the gauge may be telling you that you are running lean, but the engine runs lean all the time. it ascolates(sp?) between rich and lean all the time.
