I just had my timing chain and tensioners replaced and noticed that my idle is a little rough.I poked around the engine compartment and found a hose off but I can't see where it gets connected.I think it comes from the transmission and it seems to have been clamped to the side of the air filter box ...
It's not the chain that goes bad,it's the two tensioners.I'll have the old parts tomorrow but from what I've read here the tensioners have plastic parts.That's what wears.Mine lasted 64,000 miles.I guess this is a pretty common problem.
Mine did the same thing.I stayed with the double sided tape solution but I used more strips than Nissan did.It works well if you clean off the area real good and start from scratch
