I have a mustang v-6 3.8 that only misses at a steady speed. The only time it misses is when you have your speed up, and are maintaining a steady speed. Speeding up or slowing down, no miss. Only when foot is barley pushing on accelerator to maintain a steady speed

Engine misfires 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.
