Bad MAP Sensor???
My 1973 450 SL has a nasty black soot problem and bad gas mileage. (9 Mpg) I was reading another post about MAP sensor resistance. I was hoping someone could confirm the correct ohm values for the 4 pins coming out of the sensor. Mine has 92 ohms on the outer two pins with the connector out and 88 ohms with the connector in. The inner pair is open circuit without the connector and 340 ohms with the connector plugged in. This does not sound correct.
Can someone help????
