Jakster884 Posted April 25, 2014 Share Posted April 25, 2014 I have been having rough idle at start up and also cold starting issues. Yes I have the 6.0 POS. I have ready a few other reviews and they have recommended using REV X to relieve the Stiction I may be experiencing. This stuff is not cheap. I just purchase 16OZ at $140.00 shipping included. I also changed my oil about 1000 miles ago. Should I add now or wait until I change the oil in the next 4000 miles. I am hoping the injectors last this long. Any thoughts and or experience with this Rev X. Quote Link to comment Share on other sites More sharing options...
