Hello guys. I bought a Citroen Xsara 1.8i. Built 2000 “Millenium” the car for 2 weeks. Today I bought spark plugs, air filters, oil filters, oil, gasoline filters and will install it in the next days. My problem is: the engine sometimes goes off on the highway at short notice and then it ignites again. 3 days ago the engine went off at the traffic light, just wanted to call the ADAC there it went on again. Yesterday the same, the car goes off and wait after 2-3 minutes Can s be what with the ignition? So old spark plugs? The tank is always full. Please for feedback. Thank you and Gruss Felix
