I just changed my drivers side hpop line after the truck stalled on the side of the road. Now it takes longer to start and I have two codes that were not there when it stalled, p1212 and p0340. are these normal? it runs and sounds fine

 

P1212 is ICP not at expected level which is possible since you changed the drivers IDE line and have air in the oil gallery. P0340 is camshaft circuit malfunction. If it is running fine, clear it and see if it comes back.

Your truck will be harder to start until you get about 50 miles on it and clear the air out of the heads.

 

okay sounds good to me, I started it this morning. It still took a few more cranks but sounds fine once it starts, thank for the info.
