Hi, first time poster on here.
We fixed up and rebuilt a 2009 Challenger 180 SE, but it seems to struggle between 5000-5500 rpm. Like it's misfiring. Full throttle is fine, once we get past that RPM. I'm pretty sure we put new plugs in it last year, but going to buy new ones just incase. Any ideas ?
