2006 Volvo XC90 2.5T 2.5L Hesitation, Surge, Misfire, MIL Lamp on VIN: YU4CY59256
THANKS FOR ALL WHO RESPONDED. THE PROBLEM ON THESE CAME UP TO BE THE FUEL PUMP ASSEMBLY INSIDE THE TANK. THERE IS AN EJECTOR PUMP ON THE DRIVER'S SIDE BUT WE CHANGED THE MAIN FUEL PUMP AND PROBLEM SOLVED. TO DO THESE, YOU NEED TO REMOVE THE BACK SEAT. Trouble codes: P0089 (fuel pressure regulator circuit).
