spark plug gap?

I replaced the spark plugs in my '94 F-150 (with 302). I bought Motorcraft AFS-42C. A diagram under the hood says the gap should be



052-.056. So I set my gap and installed the plugs. It ran like crap! So, I go and buy new plug wires. Same thing! Now I'm thinking the plug gap for these particular plugs may be .044. I have noticed in the past, spark plug gap is usually OK right out of the box. Would .010 make such a difference?

sounds to me like you might want to recheck your firing order. might have mixed up a couple of wires. KB

You are right, sir. I screwed up and crossed wires. My Dad told me years ago, "don't ever take off but one wire at a time."
