With so many issues, you should really verify the below items...
- Do you have good fuel pressure? Borrow and plug in a gauge to the stock fuel rail bleeder valve.
- Are you injectors working correctly and clean? Google AUS Injection and maybe send them out for flow cleaning.
- Are you running the right plugs? Maybe switch to these, which are the best I have found - http://www.jegs.com/i/Brisk-USA/084/RR14S/10002/-1
I never heard of that brand before. Are they really that Good? Have you tried E3s, and if so, how do they compare?
