i am new here.........aloha...yes i am from Hilo Hawaii Usa....
Have a 1995 SL 500 - loss of power the other day.....after starting up warm after being parked for 10 minutes, rough idle ..check engine light on. Drive off the lot and it has no power at all...barely goes to 4000 rpm with pedal to floor...feels like 4 cylinder; however, no misfire. Rotten egg smell when light came on.
Next day changed fuel filter, not too bad, but had it off so i changed it
Wix .Fuel filter wix does not fit so i take it back and they look up the one for a 1997 and it matches the old one .....the one that fits is the one with nipples ...fuel line slips on with clamps .....my parts guy said it was for a 1997 model S L 500....Take a fuel sample looks clean, fresh, no water
Ccheck the rotors, distributor cap and plugs...all good, plugs like new bosch...look a little lean. None of them are fouled, or wet....look ike new.
Restart same problem...no power test drive no power, again a bit of a rotten egg smell.. HELP ?
thinking about clogged catalyst ? or maybe how to clear the codes ?
Also when in park I rev it up to 4500 rpm and sounds like a bit of swooshing out the exhaust like clogged catalyst.....car has 74,215 miles on it...very pristine car......air filters super clean....
Also when i bought the car 5 months ago the radio was off and i had to recode it to work leading me to believe that either the battery was dead , diconnect for a time or replaced.......could this be a problem starter ?
All help cordially invited
No good mercedes or independent shop within 100 miles ....HELP
My best guess was to disconnect the twin catalytic converters up front and run it open ....
HOWEVER---> a friend said that mercedes benz have problems with codes some time when battery disconnected or changed and need to have the codes clearded to run and idle properly......HOW DO WE CLEAR THEM..??
bottom line is i need help.... i do not have a scanner,,, my friend has a snap on scanner and we are not sure if it will give the codes and or clear them
First things first...Whats my next step please ? Grateful for all help...
