How did you determine that, "Most people just delete it after warranty and swap the valve springs and stuff."?Ah, I missed the .6vs.9 lol.
the wifes denali has it over time it kills the valve train, and they are made of gold, like $900 ish for the 4 that shut down vs $29.99 for stock or something like that.. Most people just delete it after warranty and swap the valve spings and stuff.
I wonder if the cam in the 3.9L with AFM has different specs then the cam in the non AFM 3.9L engines, I've heard the AFM lifters can't handle vary aggressive cam profiles. Maybe the replacement cam is revised to maximize fuel economy without taking into consideration what the AFM lifters can handle?
it sounds like a fun project. but these cars are cheap and plentiful. i would just get another car. after $400 you will still have a car with 230k miles on the trans and no resale valueI think my questions were just answred here but can someone please confirm for me....
I have a 2007 w/3900 and AFM. Well I am having the troubles involved in this thread. The car has 230k on the clock so it would be in my best interest to just swap in a low mileage engine rather than fix my high mileage just to have it toss a rod in a month.
I have located a 2006 3.9 without the AFM with 78k on the clock for $400. Am I correct in assuming I can swap in this engine and just haul it to the dealer and that can program the ECM to run this engine?
