FJ62 stalling part 2 (code 28,51)

I finally was able to pull a couple of error codes (the PO had busted the check engine light housing inside the dash so I had no light). I got a 28 and a 51. Since the 28 is an O2 code I am wondering if this is causing my stalling upon heavy acceleration. I started having the problem after I replaced the muffler and tailpipe (could I have jarred something or pushed the O2 over the edge?). I haven't replaced the TPS yet just in case it's not necessary. Where do I look for the 51? Thanks,
Todd

Error codes 28 & 51

Getto,

Your thread is pretty old but I thought I would ask if you found the source of this combination of error codes. My 62 had the check engine light come on last week pulling a heavy load up a steep hill and I got both 28 and 51 as error codes. Seems to be running fine though. Maybe a bit harder to start but not much.

Any ideas much appreciated.
