Any ideas?
 

I have a '93 E220 and recently I've noticed that the engine has started to stutter as I am pulling to a stop, as though it may stall.

It idles sweetly once the car is stationery. I know there's not many E220 out here, but I hope someone would be able to suggest what to check.

Any input would be most appreciated. :cool:

I'm assuming this is the M111 engine 2.2L DOHC engine.

Check:

1. Overvoltage Protection Relay. Known problem from quite a few MB models and years.

2. Might possibly be the wiring harness, but since your car is not a US model, this might not be applicable.

3. Fuel pump relay.

Oops!

Thanks John, I should have done a search first. Didn't realised that there's been so much problems with this OVP part.

Can you please tell me what it looks like and where do I find it in the W124. Ditto the fuel pump relay. Thank you (10X)!

BTW would this OVP also cause the A/C to work intermitently?

Cheers
