help with code 4

I just did the mpfi swap.
Everything seems right and i checked everythign.
The car starts right up but the tach bounces between 3,000 and 4,000.
Im getting a code 4 crank sensor and a code 10 air intake temp.
I have to ecus that both give the same codes.
Any help would be greatly appreciated.

Ok, i have found that some people have had this problem and they added shilded wire that went from the ECU to the distributor.
Is this my problem?
