Ive changed the rotor button and plug wires but still every time usually in 3rd gear after 3k rpm at about half throttle i can feel a lag at various rpms until i shift and again through 4th and 5th.

I cant feel it at full throttle but i know im still losing power from it and i just can seem to figure it out.

Engine is a b18 and it is in a VX eg.
just bolt ons like I/H/E..skunk2 intake mani, clutch and flywheel.

Rotor button was new then i noticed i had a hair crack in the dizzy so i checked the button and it was kinda burnt so i changed it.
I changed the plugs because the aftermarket plugs would not stay connected on i think number 4 on the dizzy, But plugs are good and is still doing it.
thanks
