Anybody know if TST has a fix for this yet? I got on of the 5000 model boxes and it is the newest but last night luggin around town I felt the truck stumble and now have the P 0366 to go along with my P 0191 that I have had for a while.

 

I see that most of you guys are from the ever-warm South but have any of you received the 0336 code from using your high idle feature with your TST on?

I get this about 1/2 the time when I use my high idle feature and the truck stumbling is very noticable. One time while idling up to a higher RPM the engine just fell on its face and started smoking and missing. I had to turn off the high idle for a minute and then try again?? Kinda crazy if you ask me.

I have never got the code while driving around or under "normal" driving, no such thing with this truck.
