IllustrationON OUR 1998 OLDSMOBILE THE SECOND FAILURE OF THE INTAKE UPPER MAINIFOLD WAS AT 95,918 MILES ON 08/24/2002. DOES THIS MEAN THAT GENERAL MOTOR'S INTAKE MAINIFOLDS ARE ONLY GOOD FOR AN AVERAGE OF 54,000 MILES? WE HAD A 1997 BUICK WITH THE SAME MOTOR AND SAME INTAKE UPPER MAINIFOLD THAT FAILED AT 71,000 MILES JUST TWO WEEKS AGO! DT

THE FRONT END WAS VIBRATING . THE VEHICLE WAS TAKEN TO MERCHANTS TIRE FOR ALIGNMENT AND ROTATION. I WAS ADVISED THE TIRE WERE CHOPPED UP AND NEW TIRES WERE THE ONLY WAY TO FIX THE PROBLEM AND THE PROBLEM WAS CAUSED BY WEAK SHOCKS OR STRUTS. I TOOK THE CAR TO THE DEALER AND WAS ADVISED BY THE SERVICE DEPT. PERSONAL THAT THE TIRES NEEDED TO ROTATED EVERY TWO OIL CHANGES AND NOTHING WAS WRONG WITH THE SHOCKS OR STRUTS. ALSO I WAS ADVISED THAT IF THEY WERE ROTATED THEY MIGHT WEAR SMOOTH AND THE PROBLEM WOULD GO AWAY.( DOT NUMBER: TIRE SIZE: P205/70R15 )

104V090000 · Fuel System, Gasoline:delivery
Feb 24, 2004
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH 3800 V6 (L36) ENGINES AND CERTAIN DELPHI FUEL PRESSURE REGULATORS, THE REGULATORS HAVE A MUCH HIGHER THAN USUAL RATE OF FUEL LEAKS. A LEAK CAN ALLOW FUEL TO ENTER THE INTAKE MANIFOLD THROUGH A VACUUM LINE. IF THE ENGINE DOES NOT START WHEN CRANKED, THE FUEL FROM THE LEAKING REGULATOR AND A MISTIMED SPARK CAN CAUSE A BACKFIRE.
Consequence & remedy
Consequence: THE BACKFIRE CAN RUPTURE THE INTAKE MANIFOLD. THE RUPTURE OF THE INTAKE MANIFOLD CAN DISPLACE A FUEL LINE, PULLING AN INJECTOR OUT OF PLACE, AND CAUSING A FUEL LEAK AND POSSIBLE FIRE.
Remedy: DEALERS WILL INSTALL NEW FUEL PRESSURE REGULATORS WITH IMPROVED DIAPHRAGMS. THE RECALL WILL BE CONDUCTED IN PHASED MAILINGS. PHASE 1 BEGAN ON JUNE 30, 2004, AND PHASE 2 BEGAN ON SEPTEMBER 30, 2004. OWNERS SHOULD CONTACT BUICK AT 1-866-608-8080, OLDSMOBILE AT 1-800-630-6537, OR PONTIAC AT 1-800-620-7668.
