Hi,
i was driving yesterday doing some pulls in my lexus IS 200, 2000 on the highway. After redlining the car on 3rd gear and going like 130kph it started to idle up and down. By this I mean the rpms where jumping from 1000 to 2000 rpm and back. I noticed too that my thremometer started doing the same thing, going up and down showing that the motor would be cold and then warm etc. Did I break my lamda and thermal sensor or what could be the issue. I haven’t tried starting the car after yesterday but im going to soon.
