Hello everyone. Maybe one can help me. I have a C5 I 3.0 liter. Now the Kat’s were broken and have been replaced with Lambda probes. The car also ran wonderful. Now it happens that the car runs out during the ride simply and without any indication in the dashboard. But the engine can start immediately again and runs also quite normally until it runs out after maybe two kilometers. Can this lie on the ignition coils? I have a Mechanics said that they have to be changed at my time. Would be great if I could get an opinion or a tip from you.
