What caused you to change the MAF? Was the CEL on? Did you read the OBD-II codes? Generally, when the MAF is failing a pair of specific codes are generated. If other codes are present they may indicate other problems such as the CAT's and the O2 sensors. OBD-II codes generally relate to cars emission control systems.
Limp home mode is a feature to protect your car from further damage. You are limited to 2nd gear/reverse and I believe about 2500rpm. So you are not stranded and you can go to the dealer and have the MB codes read with the STAR diagnostics which may indicate a problem with the engine or transmission not covered by the OBD-II codes mentioned above. Good luck.
