1990-300SEL 200k Bad idle-dies/Surge/Shutter
 

1990 300-SEL GAS/200K/MILES WELL MAINTAINED.
A BIT OF HISTORY-2 MONTHS AGO CHANGED ALTERNATOR. ALL LIGHTS DIMMING UP AND DOWN. WHEN GOING OUT IT TOOK MANY SPINS TO CRANK, SPITTED, SPUTTERED, BACKFIRED AND UNDERNEATH MIDWAY, GOT FIRE BRIGHT, THOUGHT IT WAS GOING TO BURN UP. WAS ABLE TO DRIVE NEXT DAY TO REPAIR SHOP WITHOUT MAJOR PROBLEM, DIED IN PARKING LOT. CHANGED ALTERNATOR AND NOW CHANGED IT AGAIN AFTER 2MTHS. IT STILL CONTINUES TO AT LOW SITTING IDLE SPEED, SURGE AND AT TIMES DIE OUT. WHEN INITIALLY TAKING OFF, IT WILL SURGE SERVERAL TIMES, SPUTTER OR SHUTTER SOUND DOWN AND SOMETIMES DIE. ONCE IT DOES GET ABOVE A CERTAIN IDLE SPEED, IT RUNS GREAT-SMOOTH! IF I STEP ON IT TO PASS ANOTHER CAR, IT WILL SHUTTER DOWN AGAIN UNTIL I BACK OFF THE ACCELERATOR SOME. WHEN IDLE OR CRANKING, I SMELL A RICH FUEL SMELL. WHOEVER WOULD BE SO KIND TO TAKE THE VALUABLE TIME TO LINE BY LINE DIAGNOSE MY POTENTIAL PROBLEM, WILL BE GREATLY APPRECIATED.
