Having problems with your 2005 Nissan Xterra ?
When my 2005 Xterra S is at idle there is a mild knocking sound coming from the back left side (as i look at it) of the engine along with (while operating) vehicle shaking like its about to die out but once i start to accelerate it's fine. This happens only at idle.
It was worse right before i changed oil (10-30W), oil filter, spark plugs (NGK), didn't change the Air Filter yet and it's still doing same thing with Service engine light on.
Not sure if you've found the solution..You need to 1) Ck the side engine mounts for cracks,you can plainly see if they are..If so replace them.2) Have the target idle bumped up 50 to 75 rpm's.It'll take care of your problem
I would get ur computer system scanned to see if ur misfire or code is even referring to anything in the left rear of engine,if it does u could have some internal damage,maybe under left rear valve cover, possibly worn valvetrain parts????
