I have the LLY with the Juice and Attitude monitor that I am having trouble with. When the engine not up to full operating temp is hesitates, misses and injector knocks when you are driving. I have sent in the unit to have the injector knock fixed but it is still running real rough. Does anyone with the Juice have the same cold truck problems?

Most tuners don't work well until engine temp hit's 160 to 180. All diesels need normal engine temp to work efficiently. Many tuners are set to not kick-in until engine temp reaches certain *F.

injector knocks are probably a different problem. If you disconnect the Juice, do you still have the same problems? mine is LB7 so you may need to PM members with LLY and Juice in sig and see if they have problems. Might want to post under LLY forum ????

BTW, welcome to the club !!! you should put your truck descript and mods in sig. and do some searches (LLY Juice). There are thousands of threads/forums and You will find an answer. May take a while. Good Luck.
