since my scraper is at the docs getting a makeover ive been demoted to a 9r, not a bad machine kinda light, but for two weeks now the air intake temperature light has been coming on, it comes on when im pushing sometimes when im ripping. yesterday we took off the aftercooler found nothing wrong the cat guy and our mechanics cant figure it out. all the fancy gismos these new machines got i figured the cat guy would hook his laptop up and presto it would tell him what part to change, guess not. has any one ever had this prob?
