93 aero v6, 2.8l. recently getting p0089 - duty cycle faults. starts and runs ok. around 60mph must downshift to accelerate, otherwise engine jerks like an ignition is too early. where should i start?
Couple of times there were P0087 fuel pressure faults, but now that is only P0089.

is there such a thing as a pressure regulator? That is a V6 2.8L, I was thinking that is a PWM pump with no return lines?

Is is a trionic fuel control system? if so-check the fuel pressure sensor-
