So the previous owner of my 96 eclipse replaced the upstream 02 sensor but used a universal that u hard wire together instead of the direct fit. My hydrocarbons are a little bit too high and I've replaced the plugs to e3s, the distributor, plug wires, and done all I can. Even had back pressure test done. Would the hard wire vs direct fit have that big of a difference to cause me to be a few hydrocarbons too high?
