I have a Country Coach FE 420 with a C9 425 hp. I have 18,000 miles on it . A 16,000 mile I had a check engine light come on. Turns out Cat said I had a blown turbo. They said they had some hot inlet air alert showing on the read out.
Cat replaced the turbo but after checking to see if everything was working fine after a few miles Cat is still getting alerts showing hot inlet air but now they are saying it's CC problem, plus now I get what feels like a miss in the engine.
Has anyone else run into this. Thanks
