Engine Shutter

[spyder1529]

Hey, I'm looking at a 325i and I honestly don't know very much about them. (how they run, etc.) Anyway, when I was test driving one (93' 120k manual) I was accelerating onto the freeway and noticed a shutter in 1st and 2nd gear around 2500 rpm. It shutters even when I'm not touching the cluch, it is kind of hard to notice unless you are feeling for it. Anyway I didn't know if it was tuned to run that way or if it was a serious problem.

hmm sounds like the car needs a tune up, could be plugs.

did you ask the dealer what has been done to the car?

p.s-welcome to the forums!

Check the guibo. its a rubber disk in the drive shaft just behind the transmission.

I haven't checked out the car sense I posted last but I called the seller and she told me the cluch was repaced a year or two ago (when she bought it). Anyway I didn't know if that had anything to do with the shutter, but she said she noticed it to. However, she said it wasn't anything new, and that she hadn't thought twice about it until I mentioned it. She says it happens with every manuel she drives. Although currently I have a diesel Jetta 5sp. and that never happens, it is extremely underpowered though so maybe that has something to do with it. Anyway I am stumped, with this new info. do you think this is normal or should i have it checked out? THANKS FOR THE HELP!

Besides the things already mentioned by the others... It might be that the previous owner didn't know how to drive a stick shift properly and worn out the clutch more than usual... it seems to me that what you are experiencing is a "clutch-chatter". It happens when the clutch has some spots that don't grip properly hence you get a slight feedback from the tranny especially in RPM ranges with a high torque (2500 - 3500) in the lower gears (where the clutch has to transmit the most force) it might also be associated with a light vibration.
