It ran the same after removing duals-not sluggish-same ...than afterwards a miss developed ( about 2 weeks after duals off..(not related Im sure)...than after reading your posts we determined a plug was bad..after only 16K miles (stock champions)changed plugs at 34K(1st time)----- & NOW has 50K we changed to Platinums- 7570(after reading your recomendation-mechanic was hestitant to do it but did because I insisted) anyway just seems a bit sluggish now... ( I also changed battery -due 0ver 4 years old) Im just giving you a chain of events,,,(I als serviced to K&N drop in at this time also) Im just making sure everthing is Ok ,,,, Making sure plugs arent issue because of mechanics be hesitant,,thanks MJB
