Spark plugs
I took my car to the shop to get wires and plugs
put on all spark plugs but one got changed the
mechanic said it was stuck in there and he did not
wanna chance to brake it or ruin the threads so he
left it in there will it be ok to drive my truck with
new plugs and wires and drive with the only one
old plug that's stuck in there or is it bad to drive it
like that it does not have any issues with the old
plug or any thang
