Vehicle runs rough and sputters at idle. RPM's hold steady at 750 to 850 at idle. There are no obvious vacuum leaks. There is NO check engine light, no stored codes, so I was ruling out a bad coil causing a misfire. It has new spark plugs and a new EGR valve. I was hoping for anywhere ideas please.
have the same problem?
