I have a problem with my 1988 300E, which I've had so much good advice from readers. It seem to hesitate when I press on the accellerator. I have checked the overvoltage relay 10 amp fuse and it looks ok. If the fuse is OK do I assume that the relay functions properly?
Now I want to check the oxygen sensor. Can anyone explain to me where I can find it in a 1988 300E, and if it is a DIY job or should I have an experienced mechanic check it.
