I changed the spark plugs to autolite copper recently. They told me its pregap so I just installed it without checking the cap. I figured it's pre gap. Can that be the issues?

9 times out of 10, pre-gap plugs need to be re-gapped

TUrned out pregap isnt really pregap loL! out the box the spark plugs were at 0.44 and i had to set it back to stock specs .054. Geez. i should always check the gap before installing new spark plugs.
