Yes, I drive an oldsmobile.
A '95 Oldsmobile Cutlass Supreme. A 4-Door sedan with the 6 cyl. 3.1 L. engine and automatic transmission that up until a few weeks ago ran like a dream.
Anyway, it putters. Putters real bad sometimes. It putters as you accelerate and it putters once you reach cruising speed, although then it feels like someone is hitting the gas with a regular rhythm. As the car drives away, it sounds like a small machine gun rat-a-tat-tatting. I should mention that it runs fine idling. A bit choppy, but really nothing like when it's going down the road. I had a local shop (not one I particularly like, but I had no choice) replace the serpentine belt as the old one had completely popped off, but other than that no considerable work has been done on the car in the last 3 months.
Now, I know next to nothing about cars aside from...you know...the regular maint. stuff. I've been all over the internet and my problem could be anything apparently. Fuel filter, clogged line, bad water pump, timing...the list goes ever on. I guess because the search parameters are so vague. Anyway, I don't expect to fix it myself (unless it's just ridiculously easy), but I'd like to know what it most likely is before I run it up to my mechanic.
Any and all help appreciated
