“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.”

“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.”

“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…”

“The plastic fuel line split and leaked fuel into the engine compartment of my mother's 1998 Oldsmobile 88. Had she not smelled the fuel and parked the car, I'm sure there would have been a fire.”

NHTSA complaint #10018870, filed 2003-05, 28,000 miles

“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. …”
