in two postings you still havent said what size motor,and the computer will need to match the donor motor as setting are changed all the time,two years is an eternity when it comes to vehicle changes from the manufacturer

as long as the engine size was the same everything on the cars should be identical for the most part. if it runs ok unless you really get on it the cat might be plugged i've done alot of those. otherwise go back over everything and make sure nothing is crossed ie; injector wires or plug wires.

when you say knock is it the motor knocking or are you referring to a spark knock if you are referring to the spark knock the timing is off.
