1987 300E Will Not Run

About 2 months ago my wife took the car to exercise class and when she came out to come home and started the car it backfired and would not re-start. I checked it out the following day and though it didn't backfire it would not run for more than 1/2 a second. I had the vehicle towed to my house and have periodically tried to start it with the same result. It will fire, run for about 1/2 a second than shut off. It will continue to do that until I depress the accelerator pedal then it won't start at all.

1985 300TD - Mysterious Intermittent Starting Problem

9 times out of 10 my car starts immediately no problem. 1 time out of 10 there is a click and then nothing. After several attempts I can get the car started and then everything is OK for a couple more days...

Here's the mystery. I had my shop check the solenoid (OK) and replace the ignition switch using the kit sold on this site. Everything was fine for a couple of days, then the same problem occurred. We can almost live with the problem but I'm concerned that one day we won't be able to start it at all.

Diesel Injector Seat Cleaning

1976 W115 300D
Do you recommend a specific tool, chemical, or (wire?) brush etc to clean the metal seat where the Diesel injector crush washers mount onto/in the prechamber? There is apparently a thin "film"/spots of thin carbon? very hard carbon in this area that seems to be very hard to completly remove, when attempted to clean this area. Some of this thin film of carbon? appears to remain after wire brushing with a small wire brush. I am looking for the proper tool , chemical and or procedure for cleaning this area.

1980 300D "passing" gear and faint whistle when turning right

If I push on the accelerator with only modest pressure (especially when the car is cold), it often jumps into what I assume is a "passing" gear. I've dealt with the problem by just being cautious with the accelarator - often, I just let up on the gas when I hear it jump into "passing" mode, but I was wondering if there's a repair I can try.

'83 300TDT NeedleBearings in Filter

I recently put a used transmission into a friends car, and adjusted it according to the mercedessource manual with the mercedessource tools, etc.

The used unit I pulled was from a crunched car ( a good sign the car was being driven before arriving in the junkyard) the fluid was clean, didn't smell, as well as no metal in the pan. The number matched (722.315). It seemed like a good donor.

It was without a torque convertor, so we used her existing one — draining it prior to installation, etc.

When we first put the transmission in, it shifted WAY better than the old one ever did — which the friend had for about 10 years. Seemed like great news, and a successful transplant.
