Hello folks, i have a little question about my 91 240's engine...

lately ive noticed while idling at stoplights, that every few seconds or so, i can feel a slight shudder in my car. when i first noticed it i kept paying attention and it does it often. i decided to see if it was just at that rpm, so i raised the rpm to  1000, 1500, and 2000  for about 1 min each and payed close attention, and apperantly the slight shudder shows itself regardless of the rpm.

what i want to know, is if this is a bad sign (which im pretty sure it might be), and if so, what is causing it and how could i fix it?

also i notice if i like, have the clutch down and the engine is at idle speed, and then i quickly push the gas down a decent amount and let the rpms jump to about 3000 or so then quickly release, the engine shudders (sways) back and forth somewhat violently, making it easily felt inside the car.

as ive made clear in previous posts, im not quite experienced with cars, but i get the feeling that these are bad signs <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt='

sorry if they are n00bish questions, but then again i am a n00b lol.

any enlightenment on these observations of mine is appreciated, thanks in advance <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt='
