Hey guys, My RC recently started to buck and hesitate horribly while driving, at just around 3000RPM it begins to buck so horribly that I feel like my neck is going to snap. It seems to do this more often then not when its raining or particularly cold out in the mornings. Checked for codes and only found a 54 so I topped up my intercooler and am now back to square one. Any Ideas? Thanks.

Check your plugs, wires and cap and rotor first.

If ignition checks don't show anything, try checking the AFM. That was my problem.

Check/replace your spark plug/wires, cap, rotor and fuel filter. Also check the AFM.
