wondering if anyone knows what is wrong with my b20b... here's the deal... sometimes my engine will begin to idle like I have big cams...which I don't... I'm running stock b20b... it sounds like a fluctuating low to high revving noise... I think it might be my ecu because I'm still running a nonprogramed Ls ecu(supposed to be b20 ecu.)... or it might be the fact that I was running my car without an intake for about a week in a half... if anyone knows why this is happening explain it to me... please... I'm noob.
