[QUOTE="tsn6186, post: 448986, member: 23617"] FOLLOW UP.....Replaced the exhaust systems from the manifold, new cats, 4 new 02 sensors, new ignition coil, new PCV value. Recalibrated my speedometer with the iCar Pro scanner for the Jscan app. No problems or codes detected, no misfire in cylinder 1 & 3 all is good. Fuel milage actually got better, transmission shifted better/smoother. GREAT!!!!. Oh but wait.....today the surging was back, still around 1500-1600 rpm. Rescanned when I got home and NOW it is misfiring in cylinder 6, P0306. NO check engine light. Any suggestions on where to go from here? SO FRUSTRATING!!!!! [/QUOTE]
