Question

I replaced the timing chains and the car will stat but it takes a couple seconds. It runs better, has more power then before. I did notice the purge valve was ticking a lot louder then normal, I'm going to get t the codes read tomorrow. Was wondering if anyone had any suggestions

Update... Was the cam sensor... Sensor 1 bank 2.

I had this problem too.  I was able to find a solution to the problem after reading articles on the Internet, but I don't remember which ones.
