Alright, to start off lets say I'm not anywhere near what I would consider to be car literate. So it started out that one day going up a steep hill my car started to vibrate and make a chugging sound, sorta like it was loosing power, and maybe ready to stall (I have a '95 olds cutlass supreme 3.4L). After I got up the hill, all was fine... this used to be a sporatic event, now it occurs much more often. The problem seems to almost 99% of the time only occur going uphill, but has once occured on fairly level ground. When it does this, the tach stays constant, at a tad over 2k, and it's geared such that it usually doesn't shift going uphill anyways. What could this be? I live in upstate NY, and we just recently had our spring thaw, would water in my gas lead to this? I'm not sure what shape my tank is, but maybe the angle it's at is great enough that going uphill causes it to pull more in? Or would my fuel filter be bad? Any ideas would be greatly appreciated!
