Everyone once in awhile my explorer will misfire when it is first started. I had some pending codes for misfire and thought it may be due to old plugs and wires. I changed them out today and thought everything was fine until it started to do it again. No error codes but it misfire at startup about 1 in 8 to 10 starts. When this happens it will confine to run rough till like second gear and then it's completely fine. I have also noticed when at idle there seems to be a very slight pulsing feel but not enough to cause the tach to jump. Any ideas on what may be causing the issue?
