silver 330zhp Registered User Join Date: Oct 2010 Location: Indiana Posts: 6 My Ride: 2003 330 ZHP View My Garage	Need advice -- engine light Hi guys, so I recently bought back my old 330i zhp... It now has AA headers and full exhaust, AA software, dinan intake.. and some other random parts... However, the check engine light is on and the code says it is a cylinder 3 misfire... I have put new plugs in it since and it did not fix the problem... It tends to hesitate when you are in the 2000-3500 RPM range at about half throttle, I dont know if it is an electrical issue or if it is fuel related...?
