My car is in getting safetied and the mechanic just called me to let me know it has a miss in the engine well it idles rough just enough to notice while idling is there an easy way to check spark plugs on an SHO or would that even be the problem I was thinking to that the guy I bought the car off of might have put reg octane in it when the car calls for high octane would that matter or
