I have a problem can anybody help me I have changed out the coil pack several times I still have two and three cylinders not hitting on my 2.3 Ford Ranger motor does anybody have any idea what this could be

 

Welcome to the forum

Ranger use two very different 2.3l engines, 2.3l SOHC Lima and 2.3l DOHC Duratec

What year is your Ranger?

Next step regardless would be a compression test, don't waste money on anything else until you verify compression is NOT the problem

 

You might try pulling the distributor to check if there are any broken/missing teeth on its drive gear. Has anyone checked the timing, worn belt or chain? That's all I can think of that might make several cylinders miss. Be certain too that you have the correct firing order on the plug wires. Good luck :D
