Angry Clk dead battery problems, Accelerator

Hello to you all..........I have a problem with my clk 200 the battery went dead for about 3 weeks(was away on hols) came back and jumped stated it but had very little petrol in the thank in reserve.... so it cut out. Put in petrol and jumped again and it started,thought it was job done but this was just the start of my probs....... had to find the code for the radio and enter it , the windows would go down but could not get back up for about an hour, then and this is the MAIN PROBLEM. The car will not rev passed 2000 and then revs drop low and when i push the accelerator there is now power at all even when floored, even when left idle revs are droppin and going up also there is a lot of smoke coming from exhaust..........any help will be greatly appreciated of course. Cheers.

Not sure without seeing the engine computer on a computer,but it sounds like you have lost your programming in the engine computer(ecu),the reason it runs like it does is because it's in limp home mode,I hope this fixes it for you,since the battery was dead it would be a high probability that is the problem.......Battery should have stayed up too,unless something is drawing power....Good luck!
