engine miss & idle problem

[Slow Six]

I had my truck in a while ago for an idle problem. The engine would not always slow down to the 800 RPMs but would stay at 950 to 1100 RPM. They thought it might be a dirty injector so they put in a can of expensive cleaner and told me to drive it. I added 2 additional cans after, plus I have always used a fuel conditioner. The problem still exists plus the last couple of times I have started up cold the engine has a miss at idle. I would like to hear from any of you that have had a similar problem and what was done to fix it. I am suspecting an injector or maybe a sensor. There is also a knock or hollow hammering sound at idle, sometimes louder than at other times. I am almost out of warranty so I would like to find a fix before it is all my nickle. The idle problem is worse with the Xzilleraider on.

as long as you reported it to the dealer before the waorrenty is up and its noted in there computer that you are having problems, when the warrenty is gone they still have to fix it as long as its noted... . How i know this cause i have done it before... . And i also have an attorney that claims they are responsiable for fixing it as long as its documented... ...
