So here's the deal - I bought the 94' 325i a few weeks ago with 73k on it.
I hadn't driven it on the freeway hardly at all before I bought it, so this problem didn't reveal itself until I had to drive the car back to the bay area, 300 miles from where I bought it from.
When I'm going 60-70mph (has happened as low as 55 and has high as 73 or so), the car being in 4th gear (I think), it seems to do this strange revving thing. It happens at around 3000RPM, where when I punch the gas a little more, it'll rise and then drop 250-400RPM, each up-down cylce being about a second.
If I downshift to 3rd manually, and boost the RPM's (as it would if you floored it or switched it into "3"), you get more power, and the problem is gone.
It seems only to happen in 4th gear at the ~3k RPM range.
Now, the other thing I've just recently noticed.... Since I have not until now just left it on complete auto mode for the majority of my driving, the transmission naturally shifts into second gear at a fairly low RPM/speed, as long as you aren't really pushing the car too hard. Now, the one thing that I notice is a slight dip in RPM's/power right before the car shifts into 3rd gear. This only happens when going fairly slow, and never really happens when I'm really punching it.
Hope I am being descriptive enough. I am sure you guys can shed some light on the stated problems (and I hope it's not the transmission)!
Thanks,
