I replaced the spark plugs about a week ago, just the plugs, and today there was what felt like a bad miss in the engine. I have driven it every day since with no problem. It isnt as bad in park as it is in drive or reverse. The car acts like it wants to die all the while shaking and hesitating even if given gas.. Please help

Engine Misfiring can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
