So revisiting my problems with my truck, It's been running really bad the last little while, seems to be missing and cutting out. I've replaced my plugs, one of the coils, fuel filter. I hooked a timing light up to it and all 4 cyl are firing. Tonight on a guess I thought maybe my Catalytic converter might be plugged, so I pulled out the front O2 sensor and it seemed to run a lot better until I got it up to temperature and then it started to cut out again at higher RPMs. So before I shell out the $ for a new cat I thought I better ask the forum. Could it have had a conflict because the front O2 sensor wasn't where it was supposed to be and was leaning the fuel mixture out to compensate or trying to push exhaust through the small O2 sensor hole and still too constricted so it cuts out? Am I correct in guessing it's a plugged cat? if not what else could it be and how would I diagnose it? (fuel injector, stuck valve, etc?)
I have had p0420 codes in the past and most recently a P0302 code. (haven't taken it in to rescan to see if it's more than one cylinder). The codes were prior to any of the work I have done.
Truck is a 1997 Tacoma with the 2.7L.
