Missing on Drive but not on Neutral
 

I have a 96 C-280 and after running for a while starts missing or skipping while pushing on the brakes waiting on the light or stop sign w. If I put it on neutral it is fine but I still feel that is missing. The car starts beautifully cold or hot and has great power. It only happens after the car has warmed up and running for a while. By the way, I just got this car with over a quart of what maybe low octane gas. I have filled the tank with super unleaded and still has more than 1/2 a tank but still missing/skipping. I tried turning off the AC to see if that would help but not. Any ideas or suggestions. Also, does anybody knows a good and honest Benz mechanic in Miami or Miramar, FL? In advance thank you for your help and Happy Holidays...:confused:

try running some techron through it for a couple of weeks. put in a bottle per tanka nd do it a couple of times, see if that helps, it could just be a slightly clogged injector.

Otherwise have your plugs check and air/fuel mixture checked if it can be adjusted.

Your cap and rotor might be worn too, how many miles ont he car?

For a good mechanic recommendation, check the good mb shops forum. I think Steve brotherton is in florida, but not sure how close he is to miami.

Change the 3 plug connectors/resistors under the 3 coils..

No rotor/cap on distributorless ignition engines

Gentlemen:

Thank you kindly for your help! Being a newbie at this car I was not familiar with its intricacies. When I opened coil/plugs cover I noticed that the first plug from front to back of the car had the orange wire plug cover broken. I don't know if that is the problem but I hope so. I will change the 3 plug connectors/resistors under the 3 coils and probably the plugs, and wire set.

If you have any other suggestions I would greatly appreciate it.

Merry XMAS and Happy New Year!!

Use ONLY Bosch Super copper core plugs on that engine

Thank you very much for your help. I changed all of the wire plugs and it is working like a charm.

Happy Holidays!!!:p
