I had a 98 Rodeo 3.2l sitting in my stall when I got here this morning, It was running terrible, throwing codes for a miss fire and MAF sensor. I lifted it up and the drivers side exhaust was cold and the passenger side was hot. I did a back pressure test on it and sure enough the drivers side cat was plugged solid. I welded a new one in there and it runs like a top now. I thought I'd share figured someone could use the info.
