Goes into limp mode? A transmission goes into limp mode. What do you mean with this?
Depending on the emission package, it could have had only two O2 sensors or four. Are you sure that the precats are cut out? Which fault codes does the PCM show? The missing O2 sensors will be shown as fault. When you don't have a.scanner, use the key dance: ignition switch off/ run three times and leave in run at third time. Odometer will show the fault codes.
