Diagnostic Code deciphering?!

Hi there,

I have just had a new engine fitted to my 156 (last one was wrecked when the cam belt stripped itself :mad: ). On collecting the car from the garage it was driving fine for about 4 miles, then the engine warning light came on and driveability became poor - lack of power, almost choking, coughing and spluttering for a while. Thankfully that has now stopped, but lack of power through all revs / gears is still a problem.
I've taken it back to the diagnostic centre who cleared the faults after the engine fit, and the following codes are apparent:

P1178 -Mixture adaption, multiplicative (bank 2, low engine load) not in range
P1177 Mixture adaption, multiplicative (bank 1, high engine load) not in range
P0300 Random/multiple cylinders Misfire detected
P0301 Cylinder 1 Misfire detected

As I am not at all Alfa Romeo aware, can anyone tell me what this means? Is this connected to the engine fit?

Thanks for any help / advice! :confused:
