Several Issues w/ Newly Installed Reman 4.3L Motor in 96 S10 Blazer

[ember1]

Been less then a week since I have had a remanufactured 4.3L motor installed in my 96 S10 Blazer and several things have occurred that worry me. Plan on contacting the shop today, but I want to see what you all have to say:
a) Dieseling. The motor "diesels" at lower speeds. I don't seem to have any power loss, just the loud grumble. More particular after starting up for the 1st time of the day.
b) Loud constant clicking chug from drivers side of the motor.
c) Twice yesterday the car just shut off, like a vapor lock. Happened after accelerating, and releasing the accelerator into a coast. Just shut down and was able to restart in neutral on the fly.
d) Motor doesn't just fire up. It struggles like a weak battery, but battery is 100%.
Could all these be related? A, B and D bother me due to it being new/different noises from my previous motor. And C, well that is just scary, 2x in one day. Otherwise I have strong power when dirving...
Any help/input would be great. Thanks
