1999 Ford Explorer, Injector Waveform
Posted to the Waveform Library on 11/10/2001

This is inj. #8 after 15 minutes of idling with a high potency dose of Amsoil PI. It doesn't miss at idle anymore, but accel still shows the leanness. The pintle hump is better defined, but still short. This is a 60psi returnless fuel system.
