I have an 06 with the 2.4 and for about 2 months now it has been bucking (like a slight miss) between 50 and 60 mph. No OBD2 codes or pending codes. It has 112,000 miles and the interval for the spark plugs is 97,500 miles, so I changed the factory Denso plugs with NGK IFR5E11 and gapped at .039 All the coils look okay, no tracers or cracks. I still have the bucking when I put it on cruise at the above speeds and the rpms fluctuate within 100 rpms when I watch the scan tool. Any suggestions?
