Hey all. Just wondering if anyone has any ideas on why i'm having a miss-fire problem between 1000-2500 rpms. It's only when i try to keep the throttle steady. It idles more or less pretty well between 1000 and 1500. Yeah i know it is high. But it's so cold here that if I have it any less won't stay going in morning.

Anyway I have B20B. OBD2. It revs up great. I just can't keep a steady throttle at low RPMS. Usually does fine above 3000 but sputteres and missfires sometimes at steady throttles then too. Slapped this beast into my 97 Civic.

Makes it REALLLY hard to drive in city. Not to mention my new clutch and all.

I'm pretty sure other people have asked about this and have the same problem.

 

I should say i've checked the timing several times. And i've changed stock cams back in and out. And i've had same problems. I've had others look at cam settings and everything says they are setup how they should be. So i'm pretty sure it's not cam settings or riming.
