just bought a 1984 190e 8valve. it has a little gremlin in it and i am locking for some help. it starts fine idles fine then it will quit . it will start right back up. some times it will stay running just fine or it just quits again. seems to quit easyer when its cold. it has tryed to quit while driving but it kicks back in and go's i was told to check the ignition module on the drivers side fender well to see if it looks like it got hot.it looks a little corroded not like it got hot. who sells a good manual for troubleshooting this? any recomendations ? ? thanks
