Hello, as the title says the engine is hesitating and bogging and the afr is going too lean 21afr, just from 3 to 4k rpm then rockets;
But if I go full throttle from a standing start and shift between gears I mean drag race, there is no problem. Everything is fine, but the problem arises when cruising then wot between 3 and 4k rpm;
Is it the maf scaling curve between these values?
Plz help
Injector duty is 12% at wot between those rpm's
