Engine jolts - my solution

My 2000 323Ci had been experiencing engine jolts between 1000-2000rpm for quite a while, but it never threw any codes. I changed the fuel filter and that seemed to solve the problem for a few weeks, then it started again. I started looking at all kinds of stuff like replacing VANOS seals, replacing the fuel pump, etc. And decided to start with a simple spark plug and plug boot replacement. While I was at it, I changed the exhaust camshaft sensor.
The car runs great now - engine jolts are completely gone - the advice here is to start with the simple things first. $115 for plugs, boots and a sensor was a cheap and simple fix.

Glad you fixed it! but consider yourself lucky, as that kind of symptom can mean many many many things, and without codes being thrown, can lead to a lot of replacement parts that are not necessary.. but you've done good!
