If you use too much it can, not severely but it can have negative effects.
Like someone said, check all the wires. It's easy to rip a wire internally too if you yank it too hard. A lot of times it'll rip where it attaches on the plug end and you may not even notice. I've done it on an Avalanche, had new wires but still...I didn't mean to.
If the wires are good then maybe the plug gap, but if you bought the plugs specifically for the car the gap should be within spec for the most part. And even if it's off a little it shouldn't be enough to do what you're saying. Unless some asshat at the store gave you the wrong ones.
