First I would like to thank you for all you do.
Here’s my problem…I took my car to Nissan for a hard cold start. I had this code P0011. They said due to low oil and they topped off and the code went away, but the hard start still happened.
As it got progressively worse I took it into another Nissan dealership and it’s pulling the P0340 code. This is a brief overview of what they said… Crank angle is 17 degrees retard fed and idle and start up. This is caused by a stretched timing chain, only the chain was replaced in.
Since then I’ve replaced 3 cam and crank sensors still leading to the same path, but worst. My car was sitting for 2 weeks in November and did not start at all. It was towed and they replaced the sensor and it started but it was shaking and losing power to drive it a few blocks. The mechanic said that the cam sensor had marks on it, which I guess the chain is marking the sensor?
I can’t not get an exact answer to what problem the car has without paying to dig into the engine. A mechanic said it might be the variable valve timing control (which I didn’t tell him about).
Other than the hard start from June- Nov the car ran fine no problems starting when it was ran for a little while.
So my questions is…how can it be a timing chain and run so good for so long and what’s causing it to not start and run bad now?
What is your opinion on what the cause might be? Do you think it should be torned into to to see or can test be ran to pin point.
Hummm, this is pretty strange….I personally have not heard of this issue before. What concerns me is it seems that you started to have this issue after the timing chain was replaced? Why was the chain replaced, did it break, or was noisy? Usually you do not need to replace the chain, it will last the life of the engine unless there is a rare part failure or something out of the norm.
