[mariesu]

hi, new user, need help with mercedes, originally came to me with cel and hesitation, had codes 150, 300, 304, 306, 305, 170. replaced plugs and mass air flow meter. code 150 returns intermittantly. while driving, car dies either under load or when slowing to a stop. code 150 sets. car restarts, but light stays on. flashes at times.
