how to test these list of components?
does anybody have any good resource for testing the following components on an 85' 190E 8V:
1. microswitch 2. throttle valve switch 3. airflow sensor 4. idle control valve 5. EHA 6. OVP 7. throttle linkage adjustment 8. cold start valve I have a high idle problem and so far what I've done to try to solve the problem are as follows: 1. new spark plugs, cap, rotor, wires (that got rid of the stalling) 2. idle control valve cleaned (that seemed to settle the idling down but only when in gear, idling still high in P and N). I also noticed that when this valve is disconnected the idling shoots up. 3. microswitch - I've noticed that when I activate the switch the idling takes a couple of seconds to go down but not a lot. 4. I've played around with the idle adjustment screw right by the firewall on the end of the gas pedal. 5. fuse on the OVP looks fine 6. my EHA is disconnected and don't know if it should be thanks in advance for all the feedbacks! |

Same as my problem. I also in Vancouver, BC. Let me know if you find out what problem. I just changed the throttle cable today, but seem look like wrong setting on my car. too bad

I'd go the dealership and have them diagnose the problem/s.
Would cost you 1.5 hours but would tell you what is wrong with your car, instead of you witch hunting for it. With that info, you may choose to DIY or go to an indie. Cheers!

My guess is a bad idle control valve or rock hard rubber boot going to it that is allowing excess air into it. Try wrapping electrical tape around to seal off the air and see whether or idle falls. How did you clean it? Haasman

Hi rfremista,
there is a book by Charles O. Probst, Bosch Fuel Injection and Engine Management by Bentley Publishers that covers the Bosch systems. I assume yours is a Bosch fuel injection system. I bought it over the internet a year ago for about $25 if I recall correctly. Good book Reinhard Kreutzer |

I'm suprprised why no one has mentioned this yet, but the Service CD for the w201 has exact procedures on how to test all the electrical components in the car. You can get the CD on ebay for $10.
