My son is at college driving a 93 LX, 4cyl, has been running fine but lately he tells me his gas mileage is way down, and has been getting intermittant check engine lite. He took it to Advance auto to have them read the code, seems its calling out the O2 sensor as the fault. So I looked up O2 sensors on Advance web site, there are several listed some with 8" leads some with 13" leads, others are generic, looks like you're meant to "cut and trim" to fit. So, my question is, which one(8" or 13 ") is correct for the 93 LX,
4cyl. ? Is this dependant on production date? What are the "gotchas" in changing the O2 sensor, you what not to do ? Remove when cold , hot, pre-soak threads with penetrating oil, special wrench needed? Any advice will be appreciated? Thanks, John R in NC
