Cordial greeting friend Diabolo. My vehicle is a Mercedes-Benz 230E, body W124 of the year 1985, four-cylinder 10298 engine, 2,299 cc lately when I am going to turn it on and even more so when it is cold in the morning it is difficult, it turns on a lot of difficulty after several attempts and the engine is very slow in its revolutions, about to try to get out again, it is also very unstable, it is very unstable. Already check high cables, distributor lid, new spark plugs and continue the same. Also in the march transacy with a normal acceleration it presents small jumps, that is, small failures. The vehicle despite its age has just 200 thousand kilometers and is very preserved. Go to your experience and knowledge to help me solve this inconvenience. In advance, thank you very much.
