Ok soooo here it goes. I recently did head work including port and polish new camshafts and camgears. How does it sound? amazing, however off topic. I was running lean after this so i put in a apexi AFC neo to give my car the extra fuel it needs to it doesnt cutt off everytime i push in the clutch. That solved the fuel problem, however yesterday i was driving a little quick, so sue me, i was revving pretty high usually my car revved up to 7500 rpm before the headwork, and with new cams are supposed to go all the way up to 8100. Around 5 to 6K though it suddenly made loud engine noise and was just staying at that rpm and i lost power. I tried it again, and my car kinda lost it and started sputtering and shaking. After that happened my car was sputtering at low rpms until i pushed the clutch in, it ran ok after that, but what is causing this because i am afraid to go up into my higher rpm ranges now. Please help!
