have posted a few times about my somking at idle problem , thought it was turbo seal , replaced turbo ,not any better , now smells more like fuel . sent injectors to DON , did pop test says they are okay. i have been reading and see some saying that when fca goes it full fuels , which could cause smoking and makes alot of injector noise . truck has lot like injector knock noise , can hear it in the exhaust .

 

You really need to get a scanner hooked up to see what rail pressure is vs. requested rail pressure to determine a failed FCA. Are there any codes? Without some particular diagnostic data, it's gonna be hard to diagnose.

 

I just had some problems with my truck is was smoking heavely at ideal and cutting out took it to dealer they could not find what the problem was all i had left on the truck that was not stock was quad boost fooler took it off and now all is well

 

well got my injectors back from don , hes says they where fine , changed the fca when i put in the injectors and everything is fine now .
