Hesitation at high revs

chdavis · Jan 21, 2017

I've noticed my 2005 F430 F1 has a hesitation in 4th thru 6th gears at speed, beginning around 6k RPM until redline. Like it's not getting fuel or something. No misfires or fault codes.

Any ideas? I was thinking spark plugs, but I'm not sure.

More like fuel pressure as you have high flow rates in the higher gears and revs- plugs would show in the low gears as well
Filters, pumps or pressure regulation ?
