Need some input i have a 2000 wrangler 4.0 just put a 4.7 L6 stroker in I'm having an issue with multiple cylinder misfires periodically sometimes its just one cylinder that's misfiring #4 I've tried almost everything that i could think of would appreciate the input if anybody knows anything about it. The only thing i can think to do is remapping the ECM because it's thinking i I'm running a 4.0 when infact it's a 4.7 so air,fuel mixing and sensors aren't acting right because the ECM thinks it's a 4.0, i think... Thank you
