So my car is making a clicking noise when entering 4 cylinder mode. I hear this with the windows down only. at around 35-25 mph in 4 cylinder mode it just continuously ticks until I am back in all 8. Obviously I could just disable dod but I read on LS1 tech that it could be my timing belt tensioner. Does this sound right? I would prefer to keep dod but if I have to I guess I wouldn't mind keeping it at 8. Shit always starts goin bad at the same time lol. I think it is time for a serious tune up.
