I just had an issue with my 2008 Chevy Tahoe 5.3L V8 with 116k miles. Took it into the shop when these indicators flashed on dashboard along with Engine light. Heard from Chevy Dealer and saying need new cam and lifters to the tune of 6400 dollars. This is not an everyday driven truck and oil changes are routine. Has anyone else had this issue???

 

afm lifter collapsed? yes its a common issue
