did you hold the throttle wide open during the test? you need to for accurate reading, as far as it sputtering, i would make sure you didnt pull a plug wire apart by accident, also check plug gap, you could have easily fucked up the gap on a plug...

i'm not too sure if holding the throttle open makes that much of a difference.

in my buddy's gsr, we held it open and got the exact same results as wehn the throttle was shut
