Hi guys,
got some questions:
I think I’m starting to have issues with afm system. How long can it go? Am I playing Russian roulette?
details:
2019 Silverado custom, 5.3
103000 miles.
started having tick around 45000 (of course after warranty)
I would get valve train clatter occasionally around 2200-2800 rpm not to often (mild acceleration not hard)
last trip I did was with small trailer (5k and towing mode on) and with cruise control the valves would start clattering every 15 min. I would turn off cruise control and let the clattering stop and resume speed.
now it’s happening a lot now every time I’m on hwy with cruise control.
would afm disabler help now? Or is it too late and should be looking for the afm delete.
is there a way to very one of the valves is bad?
thank you,
randy
