Question about 1989 Mercedes-Benz 300-Class
Check engine light comes on, then there it go,s. on cool day it will run good for a long time-until hot. it is a 300e.
It could possibly be your temperature sensor. I had a Buick with the same problem. In winter, it ran fine. When the weather warmed up, the car would sputter and die. A defective temp. sensor will cause your car's ECM to mis-read the coolant's temp. So it will adjust your fuel input as if the outside temp. was -30,causing an over-rich fuel mixture.
