Hey Forum Friends; Im trying to get 'her' Right for some Hot Las Vegas summer cruisin... 1990 300E, m103.983 engine .........
it has the 16pin LED diagnostic module...... I am getting the following 'Blink' sepuences.....

11 blinks; Air Injection System/'Emissions Air Pump Fault'

13 blinks; Intake Air Temperature

31 blinks; Intermittant Contact in Intake Air Temp Sensor

So can Anyone tell me what each blink code Means And 'Exactly' what part should be Replaced???
THANKS; In Advance for ALL Help and Recommendations..............

11 blinks: try the check air valve that is connected to the vacuum line going to the smog pump.

13 blinks: try the sensor connected to the air intake boot

31 blinks: possibly refers to the code above (13 blinks) make sure the wires are intact and that the connection to the boot is solid.
