My truck is strating to Idle rough and my mpg has droped.I have had a tickong noise for a long time that i tought might be an injector but I dont have any more smoke than normal and my oli level hasn't changed. so I am lost to whats is wrong with my truuck.could it be an injector or somthing else ??? In idea's ??????

 

Have you tried a good dose of injector cleaner and a good hrd run or pull with the truck? I would start there. Also, fuel filter. How long has it been since you changed it? They can get real dirty real fast... Start there and see what happens..

 

I've done then injector cleaner but it's been about 8000 sience a filter change so I will try that and see what happens .thanks for the help

 

I had a rough idle and was getting worried. I poured some diesel kleen, and wala smooth idle now.
