Engine Trepidation 3.0l crd Jeep Commander
Hello guys. I'm new on this forum and what brought me here is a problem with my car.
I got a Jeep Commander 2007 3.0l crd. I got some problems with an engine trepidation in low shift ( less that 1200). When i accelerate it, it starts working normally, with no problems. Few weeks ago i got some problems with the plug relay and somebody tried to repair it, but 2-3 days after that, the relay "crashed" again. The mechanic repaired it again, the car worked for some few more days, and then it started to trepidate. I went to some services where they told me that the problem is with one atomizer. I changed it but i still got the same trepidation under 1200. I tried to put it on more testers and they doesn't identify any errors... Now the services tells me that a piston doesn't work properly... I'm pretty desperate because i don't know what to do, and i'm sick of the mechanichs of my country because all they trying to do is to get more money by keeping the car in the service and changing parts by guessing whats the problem, not by identifying it. I hope you guys can help me, and thanks a lot for your time!
