Just finished the H22A Accord swap. Been running for 3 weeks now and when driving normal, its great,but at WOT, the motor hesistates n bucks like crazy especially when Vtec kicks in. This happens only in 2nd and 3rd before and after Vtec engages.

No CEL.. idles fine. new plugs,wires,caps,fuel filter, etc, etc.. full major tune up. Running 92 octane. I/H/E cam gears(+2,-2)flywheel/clutch.

What could it be? Am I running lean or something? When we dyno it after the swap was done,183 hp/151 tq, right before Vtec, the power just fell flat on its face and jumped right back up at Vtec. This explaines the harsh yank/buck right before Vtec kicks in. I still don't see why its bucking or hesistating through out the power band.

It goes something like this:

1st gear - 1k ------5k------7.8 ->smooth
2nd 4k ----..5k-.-.-.----7.8 ->harsh/hesistation
3rd almost the same as 2nd gear.

Any help would greatly be appreciated. Thanks
