Done.. I think I found a dealership willing to actually figure it out. I feel weird hoping my truck will throw a code so I can have it diagnosed.
What did you figure out on this??? I have a 2010 KC SE and I've been getting the P0300 code about every 250 miles or so after I broke over 500.. So I've thrown the code 2 times.. Right at 1000 miles on it now... Just curious before I take it in to dealership..
Are you not still under warranty?
When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the crankshaft position (CKP) sensor (POS) signal to vary, ECM can determine that a misfire is occurring.
DTC detecting condition:
* Multiple cylinder misfire.
* Improper spark plug
* Insufficient compression
* Incorrect fuel pressure
* The injector circuit is open or shorted
* Fuel injectors may be faulty
* Intake air leak
* The ignition signal circuit is open or shorted
* Lack of fuel
* Drive plate or flywheel
* Front heated oxygen sensor may be faulty
So the second dealership thought the idea of the exhaust causing the problem was bogus. The pressure tested the banks intake and ruled it out too. I had a lawyer send Nissan a letter and hopefully the will try to get it fixed. Otherwise, I might have a lemon under the law. I really hope they fix it because now that I have the truck the way I want it, I would hate to see it go. I'm pretty loyal to Nissan (my 2nd Titan). My wife is in an Armada which we bought by trading in the Xterra.
Oh, and I've gotten the code twice since I originally posted. No solution.
