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?

2006 SAAB 9-3 • 68,000 miles

Couple of times there were P0087 fuel pressure faults, but now that is only P0089.

Check/Test the fuel pressure regulator

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-
