I changed my spark plugs the other day and my car started to miss when in drive or driving, but runs fine in park or neutral. I made sure the gaps were right and all connections was secured.
Check spark plug wire connection are firm and proper. If all good have friend start vehicle foot on brake, and one foot on the accelerator holding the engine revs to 2000 or so. spray a mist of water on the ignition wires. IF miss gets worse then wires are the cause.
Merely obvious first... was there a miss before you changed the plugs as you may have put the spark plug cables in the wrong order... a mistake in side by side cylinders wouldn't be that obvious at idle.
Second... buy a bottle or two of gas line antifreeze... well buy a few as it's winter time. add one now and the next time you fill up.... if the spark plug order is correct.... it could possibly be water in the fuel it happens and the gas line antifreeze is actually alchohol... it soaks up the water.

I removed and replaced the wirings one at a time. They are not the standard spark plug wires. They are electrical wires that plug into the coil which, plugs directly onto the spark plug.
It could very well be water in the gas because it does'nt miss noticeably in neutral or park and runs good at times when driving.
Thanks Guys I do appreciate ya!
