Okay so my 2004 is giving me problems. It gives me a check engine light when I drive. My friend put his computer in and looked up the error and said something about the computer. I'm guessing it's the computer for performance, when Im 100% on the gas around 5-6k rpms it kind of stops rpms are still high but it's not pulling. I have a short ram intake and jdr(cheap) headers both eBay items. I have no idea what's wrong and such I was thinking an exhaust leak from the headers. If anyone had this problem please send some feedback. Thanks
