I have had my 155 2 L 16V Super for 10 years now, with minimal problems. She has 130k kilometres on the clock now.
Lately the injector light has been coming on, usually for only a few seconds. I have replaced the lambda sensor, but the problem is still there. She is running just fine with the light on, but it does need fixing. Only other problem is occational hard starting, but that has been there a long time.
The ICV is clean.
I do note that some of the electrical connectors are not very clean and the one on the water temp sensor has slight white corrosive residue. Can this be the source of the injection light flickering? Is there a product on the market that can effective clean electrical connections?
What are the usual culprits?
Your input will be much appreciated.
