I have a Cadillac Seville with only 56K on it and in great shape. However I have discovered a miss while at idle and can't seem to figure out why. No one in my area works on cars this age. I've replaced the injectors, plugs, wire, distb cap in hopes of getting this miss to go away. Someone told me the EGR should be replaced? By any chance do you know where my next step should take me? Thanks.

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.
