95 Silverado 1500 4WD miss

[tricks4you]

Truck had a very slight miss.  Changed plugs and wires, Pulled ac delco plugs that were gapped at 55 replaced with Stock NGK gapped at chevrolet recommended 35 now truck is missing worse, did I miss something or is the gap at 55 better?

Thanks in advance

There is no better plug than ac Delco,that's my 2 cents

What cylinder is the misfire(s) on though?

 

That would make it easier to trouble shoot the problem. Could be a bad new plug or something with another part of the ignition system.

Who said 55 or 35,Mr. Chevrolet gapped them at 35?, somebody hit the medicinal,ha
