Okay this is my situtation. My sister got 1996 Hyndai 1.8l Elantra. Now, to begin with the engine has been swapped. The new engine only has 66k miles. We First replaced the Downstream o2 sensor. Same problem. New sparkplugs, sprkplg wires, wiring seems to be working fine, also the muffler system including the Cat looks pretty healthy, but same code. The car runs good. and sounds good. still same thing anyone tell me what to look for next? she needs to get the car inspected.
