When on limp mode.. the exhaust gas would smell like rotten eggs and the engine sputters like someone capped off the exhaust pipe. I usually fix this problem by tightening the hose clamp holding the MAS sensor right where the airfilter housing is attached to by the trottle body housing... for some reason, after a long cold spell with it being garaged.. it will loosen and make the ASR light come on and shoot the engine into limp mode... after tightening, and a few start ups, the light will reset itself and the limpmode gone..HOpe this helps
