Block swap problems?
 

i swaped my blown up D16A6 block for a D15B2, i re ringed and bearinged it and had its crank milled. now the car sometimes has a clicking sound from the driver side, the check engine light comes on and the car will either start lurching forward or it'll lose power. what could be causing this to happen and how can i fix it?

What is the CEL on for?
