AC Delco 41-948 spark plug. What is the gap?
SOURCE: after I change the spark
You should check the firing order again. It sounds like you have two of your plug wires reversed.

They should be CR43TS AC Delco spark plugs. be sure you dd not crack the porcelin when installing them. if you know which one is misfiring take it out and look it over ,for any cracks and ck the gap gap should be .045 the decal under the hood should also have the gap spec.
