Just changed fuel lines and delivery valve seals/O-rings. Stopped fuel leaks and the starting is much easier.

Now, I have some blk smoke at startup and nailing at idle. Once I accelerate and drive off the nailing stops.

Should I consider replacing the injectors (220K miles) ??

Where should I source the replacements ? I did not price the dealership costs, but am wary of aftermarkets.
I plan to do a diesel purge, but I do not think that will correct.

Your comments are welcome.
