Help! slight misfire with CEL

[hoveringuy]

I still have a slight misfire with some roughness at cold start. Misfire is mostly at idle when the motor is warm.

I get an occasional CEL light while driving. It will come on for a few seconds and go away. It's code 1222 which is Lambda.

Would the O2 sensor have anything to do with cold start roughness?

Maybe? I'm more clueless than you are.

Never mind.

I'm a retard.

The CEL for O2 was because that was still fouled. The miss was because I didn't gap my new plugs right. One of them had bent and was almost touching the center electrode.

Wtf. Lol. You just dropped it in I bet. Lol. Well good job fixing it.
