Check Engine light 1995 e320 code 10
 

Can any one tell me what code 10 Voltage at air mass meter to high or low means. Is the sensor bad or wire harness no good. I got 10 blinks on the self diognostic plug by the battery which is 16 pin plug (obd I). The car rough idles when you release the accelerator for a few seconds and smooths out and hesitates between 2000 to 3000 RPM over 3000RPM accelerates fine. Any suggestions is appreciated. thank you.
