Greetings and good morning fellow Bitogers on this grey and rainy day here in Central Florida.
To begin, the vehicle: 1995 Oldsmobile Cutlass Ciera SL, 3.1 V 6 Automatic transmission, currently reading 152,410 miles.
The problem: It's really hard to describe, but while cruising at speeds between 50-65 mph, the car seems to have a slight "burp," and an irregular burp at that. It isn't constant, but random, almost like "automotive indigestion."
And it's really more of a "feeling." Try to imagine a 50 year old man sitting in his living room easy chair about an hour after consuming a large deep dish pizza with all the toppings, (those of you 50 plus will know exactly what I mean).
The car has plenty of power. Under acceleration from a total stop, said car takes off and goes with no problem whatsoever. Even at speed, (say at 60mph), pressing the gas pedal to the floor rewards the driver with constant, steady acceleration.
The car has no muffler, (hence it's name "Thunder the Wonder Pig"), and while driving the driver is able to clearly hear the motor running. There is no "miss" sound from the exhaust, (like you would hear if one of the cylinders wasn't firing properly). Even while car is "burping" the exhaust note is smooth and steady, (like the "Spirit of Saint Louis" in the Jimmy Steward movie "The Spirit of Saint Louis." - Remember when he's flying across the Atlantic Ocean and he leans out the window to look at his motor and there's that steady sound of all cylinders firing? That's how "Thunder the Wonder Pig" sounds).
The only thing I've done so far is change the air filter. I bought a fuel filter, but the weather has been so nasty, I haven't changed it yet. It's been doing this for a little over a week now and quite frankly, I'm stumped as to what it could be - so before I start throwing a bunch of parts at it, I thought I would run it past you guys for input and guidance.
I love this car but am in mortal fear of being stranded one dark night in the Richloam section of Hwy 50, (Google Map it and you'll see what I mean). If anything, I do not want another encounter with the Skunk Ape.
Thoughts, opinions, ideas?
