[MBZ] 108 Problems
OK I am having some real funky issues with my 73 280SEL 4.5. The car has never run right. When I first bought the car, the timing was way out and the car ran bad and would pop. My Dallas mechanic addressed this and changed the timing chain. The car then ran well for a while but now appears to be running super rich. Especially if left to idle for a while. I left it running at idle for about 15 minutes and it started choking up and chucking black smoke from the tail pipe when I would pull off.Another strange problem is that if you do not start the car for a couple of days, the car will not want to start. You would have to leave it to crank for more then a minute before it would start. Once it has started and left running for a few mins, then if you shut the engine off and crank it again, it would start on the button. I have replaced the fuel pressure regulator and my mechanic replaced the map sensor and some of the injectors earlier. Anyone seen these issues before? Any advice is appreciated. Regards Al

I am by no means a gasser expert, but the problem where it doesn't start after it has been sitting sounds like there is a fuel leak or a check valve that is letting fuel flow back into the fuel tank. No clue on the other stuff... Best of luck John '79 300SD On Fri, 24 Jun 2005, Ali Al-Abbasi wrote: OK I am having some real funky issues with my 73 280SEL 4.5. The car has never run right.

Have you changed the thermo time switch and trigger points?

Re: [MBZ] 108 Problems
Ho andrew!@ yup, I have similar problems on mine! While I still don't have it toaly fixed (mine won't start after it gets warmed up! I did notice a HUGE imporvment when I swapped out all the fuel lines and the vacume lines in the engine... After working on my 300d, I curse these 4.5 sels... Just a bit to complicated for my tastes... Anyway, hope this might help --- andrew strasfogel [EMAIL PROTECTED] wrote: Have you changed the thermo time switch and trigger points?

Re: [MBZ] 108 Problems
Check the coil wire. I've found that some wire sets have a carbon core in this wire and that won't work on these cars. Fuel pressure and trigger points fouled out come to mind as possible problems. Make sure the vacuum line going to the manifold pressure sensor is not leaking - this will cause very poor performance. There's a small knob on the control unit that can be turned for idle mixture adjustment. Dan
