the camshaft and crankshaft are not lined up properly?

First of all, my car sounds real lopey with that ecam in there, and with the backfiring and poor performance, a couple of my family friends have mentioned the cam and crank not being aligned properly (like a tooth off,dots not lining up)

Does this make any sense whatso ever?

 

yes it does if it kicks back thru the intake the timing is of

 

It's possible. But I would suspect the timing being out of whack or a vacuum leak before that.
