There is a hole on top of the air filter housing , using long 3mm allen ranch you can adjust CO.
O2 sensor might help too , sience back then it was service item and has to be replaced every 30k miles.
But it's better be done at the shop that does smog test and repair.
By the way , this Mercedes doesn't have MAF.

    Also before you take this car for a smog test , you better drive it real hard for about 15-20 min. ,

    I usually take them on a freeway and drive on a 3d gear for 6-7 miles to warm up cat. converter.

Replace the O2 sensor. Replace or clean MAF. Replace OVP if applicable. Run fuel injector cleaner through. Replace catalytic convertor.


All these things play a part. As long as your ignition system is in order these are the things to check. If cap, rotor, coil have not been replaced try that.

Common slave cylinder available for around $40 at Repco, will do the job. You will also need some brake fluid for bleeding it when replaced. Avoid getting fluid on your skin.

The odometer/trip meter on my Mercedes-Benz 124 series (1990) only works intermittently. Does anyone know where I can get it fixed at reasonable cost?


I do not know where you live but if you look for a speedo shop they are out there you will have to remove the cluster and then remove the speedo head and give it to them. that is the cheapest way i can think of.
