QUESTION,
WHAT WIRE IN ENGINE CHASSIS WIRING NEEDS CHECKED TO CAUSE MISS.

sounds like you might have a bad pickup in the distributor to me, was it replaced with the distributor when it was swapped out or did they re-use the old one? it is called a pickup coil or a stator, depending on who you ask. it's under the rotor inside the distributor.

yes,the new distributer came with cam sensor (pick up coil).I was woundering if something in the way of cam timing slippage somewhere ,but not probabaly the chain as they dont stretch?

Before i bought a new distributer I also bought a new one(PICK UP COIL) and installed in my old distributer still the miss and backfire.
