sputtering under load

Just put on a 10% pulley. Belt is tight...no slipping. As I sit in the driveway it revs quickly & responsively.

Under acceleration the engine seems to miss then surge. Does not feel like a transmission issue as it does this in any gear (auto).

Why would it miss while driving & not while setting in driveway? Your thoughts are appreciated!

it would be under more load and boost going down the road sounds like the plugs are blowing out replace plugs or wires
