So... I have a 1990 civic hatch, base model with the 1.5L non cali motor. Pretty much stock with the exception of a short ram intake and headers and full 2.25" exhaust and no cat. The O2 sensor was bad so I just put a plug in the bung hole and just lived with the CEL. Ran fine up until I finally got a new O2 sensor and now no CEL but it runs like crap. I've searched and searched for a definitive answer to no avail. Any help is greatly appreciated. Hopefully I gave enough info for an answer but if I missed something just ask. Thanks y'all!
