Hello, I have a clio 1 bj 96 1,2. Yesterday I drove a distance of about 100 km and when I stopped at mc donalds I heard once such a rattling noise and the engine ran unround i.e. ruttled like sow. When I then turned it off and again I had the feeling that the engine didn’t want to start. When I drove home he did not take as good gas anymore and I had difficulty driving on.I pressed fully during the 2nd course but it didn’t happen much. r motor ruggles like die sow. I thought it was the belt but the noise comes more from the engine block.. What could that be??
