My girlfriend has her 1989 300e which seems to be misfiring. When she
starts it you have to give it gas and then it will idle by itself. When
she takes off it does the usual thump thump and when it idles if you go to
the muffler you can hear it going puut puut....ect. I highly dought it
will pass and emmisions test this march. IS there anyway I can fix this.
Everythign else works fine. How much does a top overhaul cost on this
motor? Regards, Chuck
