I just bought this used car on jan 1, 2013. I noticed a smell from the car but wasn't sure what is was and bought the car anyways. Well a couple weeks later my boyfriend was checking my fluids on the car and noticed a fuel leak under the hood, so we went to auto zone and bought a fuel line that cost around $30, he put it on, still leaking, well we figured since the fuel line that we bought wasn't precrimped it wasn't going to work, so we went to the junk yard and got the exact same part off another 1998 Oldsmobile 88, figured since it was precrimped it would work, not the case, fuel still leaking under the hood, so we went to the Chevy dealership in nashville and bought the very last fuel line in the state around $120, which the difference between this one and the other two is that it is 6 ft. …
While merging into interstate rush hour traffic with no warning engine failed causing lost of braking and steering effectiveness. No warning was received. Vehicle was towed to dealer and upper intake was found cracked allowing coolant to enter combustion chamber. One week and $800.00 later car was "repaired" vehicle continues to experience fuel delivery problems. Hard starting, random stalling. Dealer advised me this is a common problem with the 3800 series ii engine regardless of mileage or type of use and maintenance. Considering the sudden lost of all power this is very dangerous as braking and steering effectiveness is reduced as is electrical power for accessories such as headlamps and windshield wipers.
My 1998 olds 88 backfired upon starting and blew up the plastic intake manifold. The force of the explosion destroyed the engine cover and the fuel rail. The engine is the 3800 v6. The vehicle has 21,000 miles but was older than 3yrs, thus it was out of warranty. Because GM would not offer any financial assistance for the repair, I had it repaired myself. The explosion was caused by a leaking fuel pressure regulator that vented back the intake manifold thru a vacuum line. This situation looks to be exactly like a recall on very similar Buick cars. It was NHTSA recall # 03V473000 on nov 12th 2003. I believe the recall should be extended to cover vehicles like mine.
Tl contact owns a 1998 Oldsmobile delta eighty eight. The contact stated that the vehicle failed to start on the first attempt and shut down at stop lights and stop signs. The contact examined the vehicle and discovered gasoline in the fuel line. This same failure was discovered on two prior occasions. The vehicle was taken to a dealer once before ,and the fuel pressure regulator was replaced. The vehicle failed to start again and had the same symptoms as stated in recall # 04v09000. The contactwas uncertain if the vehicle was included in the recall. The current and failure mileage were 113,000.
The manifold on the consumers vehicle was replaced at his expense one year ago and now there is a recall on the fuel pressure regulator, which the consumer believed somehow affected the manifold. GM stated the defect did not affect his vehicle. After the engine was warmed and started, it would take a couple of tries and then the vehicle would surge when starting. The fuel pressure was leaking. The vehicle continued to lose coolant.
While entering my garage at a slow rate of speed and my foot on the brake, the car suddenly surged forward. This has happened 3 or 4 times when coming to a red light or stopped vehicles over the course of the year. I remember the Audi that had the same problem. I really thought I'd end up in my living room. I quickly put the car in neutral on all occasions. It seems like the transmission isn't dropping down to it's low range. Help.
Vehicle stopped running. Consumer had the vehicle fuel regulator repaired on two vehicles, same year, make and model. A recall was received by the manufacture involving only one of the vehicles, and reimbursement will be made for the one vehicle that was included in the fuel regulator recall. The consumer's second vehicle was not included in the fuel regulator NHTSA recall 04v09000.
I went to start my 1998 Oldsmobile 88, when I heard a loud pop when I turned the key. I turned the key off, and smelled gas and antifreeze. I opened the hood and found that fluid was leaking from the back of the motor, above the heads and below the intake manifold. My intake manifold gasket had ruptured, spilling fuel and antifreeze out of the motor.
1998 Oldsmobile 88 recall concerning defect on the 3.8 v6 engine. The consumer had to have the same recall repaired twice, the first time the manufacturer reimbursed the consumer some of his money, but the second time the manufacturer refused to reimburse the consumer. Recall#04V090000
The vehicle's manifold ruptured prior to recall notification. The consumer requested reimbursement but was denied. The consumer was denied because the part replaced was not the part covered by the recall.

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.
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.
