I purchased a 2000 Grand Cherokee w/ a blown motor 4.7L V8 [N]. 149000 miles replaced the motor with a 2000 G/C that has approx 114000 miles 4.7L V8 [N] everything went together very well BUT when I started the motor the engine light came on and eror code is 601. Question can I replace the PCM /ECM with one from another 2000 G/C or?
have the same problem?
