Hey Steve One more thing. When you're done, leave the air filter housing off when you start the engine. Let it run for a few minutes while you CAREFULLY check for leaks. Seeya

Thanks for the tips!!!

I will try and get it done this weekend time permitting, but I know that it will go much smoother now that I have been given these quality tips.

I'll let you know how it goes! And I think I'll try and take pics alog the way throughout the job.

Thanks
Steve

So, is your car running better? Was it the fuel distributor or the fuel injectors?


Thanks

Just got the parts on tuesday and had been fighting the Voltage Regulator problem ( see other post about "Spewing Battery"). So I have not installed the injectors yet. Gotta try and find a simple diagram about how these things are put together. I have got some good tips from the forum about precautions and procedures so I think if not tomorrow...then definitly next weedend.
I'll take alot of pictures..I like pictures to help explain.

Steve,
Your pictures in the "spewing battery" post were great. Thanks for taking time to post it. I can't wait for the picture instructions on installing fuel injectors. I got a 91 300E and wanted to install injectors. The repair manual was useless in detailing step by step procedure. Thanks.

Well Crap!

I tried. I got the breather off and loosed the first line off of fuel distributor. But I couldn't get the line of the top of the front injector and then I checked and my 5mm allen wrench was a mess. I had been warned about being careful here so all things being what they are, I decided to be prudent and have a pro do it. My shop owner is a pretty good guy, so I'm gonna ask him to let me see him do the first one so I'll know better next time.

I have just finished reading all the posting because I too have a rough start only in the morning. The engine will miss for just a second and then smooth out. It has been doing this for at least 2 years so I havent been too concerned. This morning I tried the advice of waiting until the pressure builds up and to my surprise it started fine without missing. My question is 1. Is this common with this car? and 2. Should I be concerned to have it fixed?

This forum is extremely helpful!

I'm having the same problem too on my M103 300CE. I have replaced the following:

1. Fuel Filter
2. Spark Plugs
3. Distributor Cap
4. Rotor
5. Ignition Coil
6. Ignition Cables

Its not an irritating problem but whenever I start her up after a few hours sitting, it'll do what you guys have described - idle rough for 3-4 secs.

I want a healthy start. Any solutions or tips? I've gone to mechanics with differing views. Some even suggested replacing parts I have already done. Oh well...

Hey 850R, any solutions or tips? Read this thread and you'll have all the tips you need!!!

Hi Buddy:

Just read your post, and I had this same exact problem on my car. My problems were when I tried to start it after it sat for awhile, it was shake, shimmy and get all crazy for about 5-7 seconds, and then smooth out and everything would be A-OK.

I took it to the dealorship, and the first thing that the tech. though of were VALVE SEALS. I have the M103 (190e 2.6), and they're known for getting old and brittle.

He replaced the seals (about $275), and it's been like a gem ever since -- no hard starts any more.

I seem to ALWAYS suggest valve seals when I post ... I'm bound to be right sooner or later!!

Best wishes-
Michael.

Thanks Michael,

I agree that they can be troruble, but I just had the head redone in September and the rought starts continued.

I have planned to have my shop replace the injectors for me but have not had the time ( or taken the time) to do it yet. This one of those problems that won't stop you from driving and enjoying your car, but you know you should take care of.

I keep hoping that I'll find some information or diagaram or something that will clear up how to do this job and allow me to confidently do it myself. But alas!

Anyway....thanks for the input. This forum does great things for MB cars and their owners.

Steve

Hi Steve:

Best of luck in getting those injectors taken care of. Do you, by chance, experience any fuel smell? I had a GM car when the injectors went bad, and I couldn't bear the stench in the cabin, even with the vents off!!

Guess I'll have to save my valve seals for later.

You're so right -- this just the best web site. Even though I'm not a DIYer, it helps to know how much it will cost so that I can have my coronary and get it over with before I take it in for repairs.

Take care and GOOD LUCK.
Michael.
