Hi I have a dodge durango 2006 4.7 v8 4 * 4

The problem is as follows. We change sonenoids, depression sensor, oil, filters. But when you drive and it goes at 1500 RPM and about 40 miles it starts to vibrate, if it accelerates or decelerates it stops I want to know if anyone has had this problem or what could be thank you very much for any help.

Postscript, I review everything that throttle body, spark plugs, coils and everything well.
