Motor misses and backfires when put in gear and while driving idles good just all of a sudden started doing this after putting a bigger set of tires on. Changed plugs checked all vacuum lines, ran injector cleaner, still no change could it be a week coil pack

Is there a check engine or service engine soon lights on. If so what is the code(s). There is a few things that can effect engine performance. Enough air and fuel in the right mixture, enough compression, spark at the right moment and timing of the pistons and valves.
It could be a weak ignition coil.
