Hey Guys (and girls?), i am new and i am having an issue. yesterday i redlined it in 1st gear (on accident) and then it started to run rough above 4500 RPM, and today it started fine, still had the issue of running rough above 4000-4500 Rpm. went a little more that a mile. i know it is getting fuel, unsure about spark. any ideas. is it just the plugs?

 

How is your oil? Do a tune up and inspect oil for anything abnormal.

 

Check that the timing belt didn't skip.
