Hello to the SL community, recently I am proud owner of an SL 55 Japan import verifiably 1 vehicle holder. Car has 115 Tkm. On the highway at the test if the car is locked off I noticed that suddenly the car from 210 km/h no longer took up gas as in emergency run but the speed rose nevertheless to 4500 rpm. So off to Daimler workshop and they switched the lamda probe. I drove beautifully in the Black Forest today brake speed up brackly as it belongs… then on the highway and full throttle .. at 220 I stopped because I thought everything was ok again and it was dark. Then I test again and there it was again .. times at 180 and later at 210 nothing goes anymore .. no interference display no noises nothing… what’s going on there?! Can someone give me a tip from his experience or knowledge perhaps ? Thanks and greetings from the Black Forest Nesh
