OK I have just replaced the intake manifold on my 08 E350 and now I am getting misfire on Cylinder 1 2 and 3 I believe I got the manifold gasket back in the right position but cant be sure HOWEVER IF I got it wrong surely I wouldn't get a 'misfire code' I would get a 'lean' code.
WHAT the hell is common to cylinders 1.2 and 3 perhaps I damaged something that is common to them, ALSO are cylinders 1,2 and 3 the ones on the right of the car ??
URGENT help needed this is the wife's car :).

Actually, you might well be getting misfires on cylinders 1, 2, and 3. My S600 TT is currently getting them on 1-6, i. e. the entire bank. What I did was put my SDS on this car and have a look at the ME-SFI section, then Actual Values, followed by the smooth-running test. That'll tell you if you're getting misfires, and sure enough, I was. Does this happen just at idle, or does it happen also when you're revving the engine? In my case, it was only at idle; revving the engine up to even 1,000 RPM kept the misfires from happening.

And yes, cylinders 1, 2, and 3 are on the right-hand side of the car, from the perspective of sitting in the driver's seat and looking forward.

Thanks for the response, I discovered what the problem was (my own fault) when I put the new intake manifold on I had the gasket 'slightly' out of alignment (although I would have sworn it was correct) and it partially blocked number 3 injector port and because of the misalignment I was getting what is known as a 'lean misfire' , when I installed the next new gasket I held it in place with some sealant and tape making sure not to interfere with the intake ports, now it runs like a dream but boy oh boy did this take some finding.
