make sure you have the spark plug wire going to the right cylinders, and if they are a weak spark, get some new ones. Also could be your timing is off.

when did this problem start? Was it acting up before you put all these parts on? It sounds like you may have installed the camshaft sensor incorrectly. I've put one in before and it can be a little tricky. Just because it drops in doesn't mean it's aligned right. Double check your install with proper instructions on hand.

either it is out of time, or you have the spark plug wires connected wrong
