Hi All,
I've done some searching around the forum, and I see alot of guys have the same problem I do- my '87 Cherokee (235K miles) gets lousy mileage, with alot of soot coming out the tailpipe. Most everyone who had answers about this on the forum believed the engine is running rich and to replace the O2 sensor.
Can anyone give me any pointers for doing this? I did a search on o2 sensors on the forum and came up with alot of stuff, but didn't see anything specific about how to replace one.
