OK I read as many post as possible first.

Here's the deal. I have a 91 300E 4Matic with 125K I bought about 4 months ago. I installed new MB\Boch plugs & wires ASAP.
The car runs great. The only weird problem is that intermittently during the cold weather in MN, the car wants to be a ***** to start after sitting for over 12 hours. It will always start if I go through this routine. I turn the starter and it doesn't fire. I wait 5 to 15 mins and turn it again and then it fires a little. I wait 5 to 15 mins turn again it fires even better untill it starts. This may be a 2 turn to 5 turn process. Most of the time it just starts quickly. It always starts and once it does it runs fine and I don't have any warm start problems. Note I found fuel injectors in the trunk so I assume they were replaced. I also used some Techcron concetrate(fuel injector, Valve, combustion chamber cleaner)

Whats the deal with this???????????
