well....help...please
 

I picked up a passat for CHEAP.
it runs.....but EXTREMELY rich.
it runs like crap, and tries to die out when you try to add any throttle.
It has 223,xxx miles and a lot of electrical problems.

I was thinking about a VR6 swap.....but idk what to expect with matching up the harness and so on so forth.

should I even keep it??
or should I sell it?
