Car Revs up and down.
Hey all, Can someone help me please? I have a 1998 323is with 100,000 or more miles on it. To explain, I will tell you how my day starts. I get in the car turn it on and it revs up and down on idle. Drive to work, as i excellerate it gives a slight jerk. Not neccesserely when the car shifts gears but i can fell a little constant jerk. Then I get out and I here this shh shh shh sound coming from the engine. Sometimes the car acts normal but it is always garunteed to do it again. So now it is getting worse. I can fix it I just don't know what I am fixing yet. Sorry for the misspelled words, Google chromes spell check suck!
