Hi. I noticed that sometimes when I'm at idle with my car it "shakes" a little. Going up and down a few 100 on the idle.Almost like a small misfire.
It happens random. Sometimes often, sometimes good for a long time. Warm or cold. Not really sure where to start to look? Spark plugs? Map sensor? Ignotion coils?
Today the fault lamp lighted up. First time while the problem have been going on for weeks.
Even harder to check as it happens just sometimes.... It's my first MB so totally lost where to start =)
Anyone have any advices?
Here is the scanner report.
Thanks in advance.
