Hi all at Mersedessource and Happy Holidays to you. I just received the diesel purge you sent me just in time for Christmas and I am dying to try it. I only have one question. Kent's instructions are very explicit but being retired from the training and education field people sometimes interpret differently no matter how precise the instructions. That said, my question is this. It appears that I will be feeding and returning the cleaner from the same bottle.

My 1977 280E seems to have a miss in it when it's hot. It's got new gas, new plugs and plug wires. Has Electronic Ignition. Fires up pretty easily but idles fast until it's put into gear, emmits a lot of smelly smoke (white/grey). Engine seems to stumble more when it's accelerated. Car sat for a 2 years before I got it. Could this be something with the vacuum system? Is there something that controls the idle speed as engine warms up and the engine timing that might have a leak or rotted off?

Hi all and happy holidays. My car runs great and is easy on the eyes too, but something has changed recently. When I left my climate control unit set on auto and the temperature wheel on heat (in the red) the blower would not switch on until the engine and coolant were warm, thus blowing warm air. Presently for some reason the blower fan comes on shortly (10 seconds) after start-up and consequently blows cold air until the engine and coolant warm. CCU? Water temperature sender? If so which one? Any takers on this one.

My automatic transmission in my 1977 280E does not lock when placed into park. When the car rolls with it in park it makes a clicking sound. I think there is a part on a transmission called a parking "pawl" and I think it jambs into something that acts as the lock. Don't know how it works on this car but I'm guessing that it must not be fully engaging and is the reason for the "clicking" noise if it's partially engaged. Please let me know if there is an easy fix for this. Thanks.
