What causes this power struggle where the motor gives more power irratically for a pinch of a second and then backs off for a pinch. I believe I have a fuel mixture problem where the system isn't suppling a consistant ratio of fuel and air. Is there a fuel/air management system that may be bad. All vacuum lines are new. 93 octane is the fuel. Installed SPG9 injectors, RRFPR and APC2 with no improvement in the irradicate surging. Lots of power but a "bumpy" lift forward.
