Welcome to DF. Moving this to the 3rd gen Ram section.

 

What code do you have?

 

I bolded your problem.

Sell it and buy a Hemi

 

Evap won't cause that. However if whoever did the timing chain is off a tooth that may. Why was the chain replaced?

 

The timing chain was loose and stretched out

 

Make sure the PCM memory gets wiped. Get a cam/crank relearn done with a scan tool. When they're in there ask them to look at the Cam/Crank degree difference in the PCM data.

Which EVAP code is it?

 

Ha. Loved the delivery on that.

 

You can also reset the computer but unhooking the battery for a few minutes...unless you have a hand scanner, then you can just clear codes and see if they come back.

It's probably worth it to get buy a hand scanner too btw, I use mine a lot and you can get them cheap.
