Hi guys having problem with my old baby 2000 e430 sport(120K)/that i keep in the garage must of the time/i have notice that the car has lost power little by little to the point that you press the pedal to the metal and it lags to reach 5-6k RPM
slow as turtle than again my daily driver i cannot compare apple to oranges. but i remenber this car had more power and lately all the sudden it start misfiring/and occassion it shuts off/the CEL came on and the code was P0100 mass or volume air flow A circuit/ I went a bought a new Maf sensor at the stealership and the same BS. So got tire and took in to the local Merc Dealer
and they said that the problem is all four Catalytics are plug up/inside and it will take $1600 to replace all four of then and of course i told them NO WAY.
Not until i check with my extended family in MB world. Sorry for the long tread guys. The car runs ok one day the bad the next. What do you guys think? thank you in advance! Ohlord fill free to chime in
