Also...be sure to check your brake fluid, tires, alignment, and anything else you can think of that I might have missed. First and foremost...get a way to scan the car for important parameters...the most vital being KR (Knock Retard). Best bang for your buck way to scan is by purchasing (If you have an Android phone look into something called the Torque App as it does everything a scan gauge does but for QUITE a bit less) an Aeroforce Scan Gauge. You can buy them on plenty of the vendor sites for around $200-$300."
