Engine Performance problem
1989 Mercedes Benz 300ce 6 cyl Two Wheel Drive Automatic 130 miles

When I start the car from cold.I have to warm it up by holding the gas pedal to higher rpm's for about 4 minutes or it runs really rough or dies, after it warms up it runs a little rough but it doesnt die,SOMETIMES after it warms up it runs as smooth as glass???

Generally it's a temperature sensor issue, Can be called ECT(engine coolant temp) or CTS(coolant temp sensor).
