| Message: | 86' 535i. Cold starts very rough idle with raw gas smell. At cold start I get an extremely rough idle for about 30 to 45 seconds with a raw gas smell. No leaks in the lines anywhere. My thoughts are: 1. a leaky injector. 2. a faulty temperature sensor. Would a faulty temp sensor cause the raw gas smell? Smell is most prominent at the passenger side front corner. Car idols fine when warm. Any other suggestions. Thanks for help. Paul | ||||
