I just purchased a 1988/ 300E with 134000km
(78000miles) and notice the check engine light comes on intermittently when idling and goes off one the car runs for a couple of minutes.Any suggestions?
I am told it could be O2sensor???
Are there generic O2sensors that can be used?
Also need a cd rom version of repair manual??
Thankyou for the input.

Hi,
It sounds like an O2 sensor to me, also. That was the only input that would turn the check engine light on and off at times other than a possibly faulty CIS-E (fuel computer) control unit, but that is very rare. I would suggest using a factory Mercedes-Benz O2 sensor for best results. Good Luck!

There are many grades of O2 sensors, stay w/BOSCH. This car uses a 3-wire sensor & the wires can be spliced w/care. If your car is a California version then there are other possibilities.
