mbzr4ever, and all,

With my car humidity and/or outside temperature do not seem to be a factor because it has had the problem in winter or summer humid or not. Because I do drive the car regularly, it doesn't break down often. When it does stall out though it is a real pain and potentialy dangerous with cars scrambling and cutting each other off to get around.

If your car is not fixed, and stalls out again, have someone turn the ignition on while you listen at the right rear wheel well. the fuel pumps are under the car just in front of the right rear wheel. Actually do this anytime so you will be familiar with the sound from the pumps. When the ignition is tuned on, the pumps will run for about 2 to 3 seconds then stop.

If your fuel pumps do not run, there is a systematic test procedure to isolate the cause. Please do not replace pumps, relays, control units etc.

Distributor caps, rotors, wires etc do wear and fail over time but they can be inspected and tested. (keep all good old parts as spares).

Yes there is a large rubber "O" ring seal in the distributor area. I'll try to get a pic.

My car has about 180 k kilometers.

Please do not replace the coil just yet.

Do you have a volt meter or multimeter?

Take care all,
Acky
