Exclamation o2 sensor hell

i just put in a new engine, 2 days later the check engine light goes on with codes reading for the vacuum hose, after changing that, the light returns on. the new codes read p1131 for the o2 sensor. after changing that, the next day the car started bucking and the speedometer is jumping all over the place. could it be a bad sensor? i hope it to be that simple...HELP

Re: o2 sensor hell

I'm not positive, but I'd change out the MAF, TPS and IAC sensors. Then at least you don't have to worry about replacing them for another 60K
