Firewall insulation pad replacement
1991 560 SEL - I have the engine out and would like to replace the firewall pad but the 4 pieces that comprise it cost a total of $970 from dealer! I've checked Dynamat but would rather get an OEM replacement. Dealer said that the padding glues onto firewall, I also heard that the padding is held on by rivets & screws....any advice?
Thanks

1981 240D Idling rougher after valve adjustment
Before valve adjustment, car idled fine. Immediately after valve adjustment car idled fine. Probably after 1,000 miles of driving, car idles rough at a stop in drive or in reverse but idles fine in park. Another change is that it has gotten cold. This was a florida car and not used to the cold. I did install a block heater from you which helped with cold starts.Turning the idle adjustment knob on the dash to the left increases RPM and helps idling.
1.How do I adjust the idle so it will run right again without having to adjust the idle knob on the dash?
2. Is it ok to drive the car with the idle adjustment knob turned to the left a little bit?

82 300D: Starter slow/nonexistant, replacement needed?
I have an '82 300D. When I try to start it, especially when it's cold, the starter works very slowly and feels like it is about to die. Seems like a dead or dying battery, but tested it and it's fine.
However when I hit the gas pedal when cranking, it does catch and start. This problem is especially harsh when the car is cold.
Do I need to replace the starter? Is there something else I'm missing? This car is my daily driver and I use it to cart my kids around and get to work, so I'm afraid to be stranded.
Thank you!

1985 300CD Electrical Fuse Problems Circuit 8
I have an issue with my daily driver. It is starting to get cold here in New England and would like to solve as quickly as possible. I am pretty handy mechanically but eletrical problem solving is not my forte so hopefully someone else can suggest some things to look at.

1975 240 D Electrical Power For Radio
I do not have any power to the electrical supply to the radio. Just bought the replacement fuse set from Kent and have cleaned all terminals and replaced every fuse. On the fuse box lid there is not an indicated fuse for the radio. So,,maybe I am not looking in the right place. Where is the fuse for the radio supply?
Thanks,

1984 300D Injectors Replaced, still rough
I just purchased some rebuilt injectors (the Monarchs on this site) and replaced them over the weekend. I did a valve adjustment while i was at it. Put everything back together and she started up after some cranking, but it didn't fix the very rough running of the engine. I'm happy to have the new injectors in there as I was due for them, but now I have to run down the problem. Think it could be the injector pump? Seems like a cylinder may not be getting fuel, or perhaps very little fuel. How can I check to see if the injector pump is working properly (or any other ideas)?
