I am having trouble with my 06 Pacifica, it is idling rough and it started hesitating and then it would
lurch and rev up to about 3 or 4000 rpms. This happened about a week or so ago and I saw on one thread about the egr valve which I replaced. Any help would be good. It has 154xxx miles on it.

 

I might suspect a sensor. Maybe the MAP or MAF sensors. Maybe throttle position sensor??.. Check for vacuum leaks too. A little more info would help. Does it do this all the time or intermittently?
