I know it's most likely a sensor and I plan on getting it scanned. However I just replaced the ECM, plugs and coils and alternator. Is there a chance the ABS sensor could have been a part of the ECM failure? Car is running fine now. I had a coil go on cylinder 4.

check to make sure #5 spark plug wire isn't bad,make sure you have not wired it wrong from changing plugs. You should purchase a chilton manual if you haven't already

I beleive your firing order is 1 3 4 2. 1 and 4 are companion cylinders-meaning the piston is up or down at the same time i.e. compression and exhaust stroke both pistons are up and even on the exhaust stroke the ignition fires in order to burn unburnt fuel/ h ve you checked your trigger. There is a good coil testing tool that is placed over the coil and has a magnetic pickup that allows you to see if the coil is being triggered-just because you have power doesn't mean that you will have spark. I would replace your ignition wires and look at your wiring harness very carefully- if it is very brittle and you see bare wires exposed that is your most likley problem because the trigger is working for 1 and 3 and has the crank senser input for all for spark plugs and the cam senser is used for ignition advance and your fuel injection system. try wiggling your harness and see if your coils start to work. wireharnesses are a major problem on mercedes benz vehicles of that era. I hope I have been helpful

a speed sensor on the front,have the ABS system scaned for the codes(this will show you wich sensor is bad)

I would be thinking that there is a good chance that you need to be checking out replacing the computer, if you aren't getting any communication with the proper scan tool then the computer isn't communicating with anything in the vehicle...... I would have guessed first off that the ignition control module might be bad but that is obviously part of the computer also, I would be looking in that direction.
SOURCE: i have replaced all 6 coils and plugs and the
start by disconnecting power to each cylinder, one at a time until you find the cylinder that does not affect the idle speed. This will be the dead cylinder. If you have spark to this cylinder, impulse to the fuel injector plug and compression is good then replace the fuel injector for the dead cylinder. Normally your check engine light will be on if you have a misfire. by reading the codes you will know which cylinder is at fault.
