Hello fellas , was a nic3 day decided to take the car out for a spin. Got on it a little to about 4500 RPM max. Now the car is misfiring or something, it's definitely not running on all cylinders was running perfect before they pulls. I'M RUNNING plugs 3346 ngk br7ef put a scanner on the car no engine codes. I changed the plugs nothing still doing the same thing. It's rough in the lower RPM range taking off but isn't so bad when you get past 2k RPM where should I start?
