That's not a timing problem. You have a misfire, and by the sounds of it, multiple cylinders are misfiring. The spark plugs and wires are the logical guess, but you also have to consider loss of compression, non-firing fuel injectors, and other engine mechanical problems.
Also, since the spark plugs were recently replaced, a common cause of this problem is one or more spark plug wires that didn't get fully-seated. There will be arcing from the terminal to the spark plug at first, until that terminal burns away far enough to cause the misfire.
