Dog sputters when opening up on the throttle

[KROGOTH]

Sometimes not all the time, if I open the throttle up, especially on second gear,
it kind of sputters like it cannot take the throttle. Is it a spark plug issue or is it a gas issue?:bang:

I would try running some SeaFoam through the gas tank. Then maybe its time to rejet?

Adjust your accelerator pump

If it was running fine earlier it could be many things. But here's a list to start.

We are working through the misfire under acceleration problem currently on an 2007 EFI dog. Our next thing to try is the crank position sensor.

Spark plugs
Spark plug wires
Ignition coil
Crank position sensor

Will add to this... Pull the float bowl and clean it and blow out the jets. Dirty gas will cause them to clog up
