Hey everyone, first time owning an Honda civic and I'm running into some issues, the car will run for about 5 seconds than die and throw a p0141 code witch is an o2 sensor code I go and unplug the o2 sensor by the engine block in the top of the exhaust manifolds and fire the car up the cel light comes on as expected but the car idles fine for about 10 minutes than dies once I try and move it the car bogs out and dies, the previous owner put an after market exhaust on its stock exhaust manifold and 2.5" exhaust the hole way with a muffler and a catalytic converter about under the center console but I don't see an o2 sensor in it, I'm at a lose with what to do. I'm still going at it tryin to figure it out any help would be muchly appreciated, cheers🍻
