Miss at idle speed 99 4.0
First off I am not a mechanic by any means.Problem all started with CEL.Changed plugs with motorcraft platnium and wires and had new upper intake gasket replaced.Cured CEL but I have this miss at idle really noticeable in drive at stop signs,red lights sometimes I can feel a sputter cruising down the road at a steady speed.Noticed my mileage has dropped a little but I'm thinking,hoping that it's due to the colder weather here.If someone could offer some suggestions to what I could look for I would really appreciate it as this sputter really bothers me.Seems to accelerate really good,also changed fuel filter and pressure is good.Also cleaned MAF.Some one has suggested EGR valve?If anybody could help with this I'd really appreciate it!!
