Two questions for you guys this morning.
1. My 2011 Versa keeps throwing a P0172 error code at me. It's really odd because it will fix itself sometimes and stay off for about a week then come back. It's funny because every time the error code light comes back on, it happens within the same 1/4 mile stretch of road every single time! I've tried using a bottle of SeaFoam but that only helped until that tank of gas was gone. I've also checked for vacuum hose leaks, and switched from mid-grade to low-grade fuel after the first time I got this error code. Why would this error code keep popping up after it goes away?
2. I have an ODB2 scanner tool which was a gift to me. It had worked previously for about 3 months and I thought it had broken and quit working but I tested it on my wifes 06 Trailblazer this morning and it worked fine. However when plugged in to my ODB2 port it will refuse to connect. How can I diagnose my ODB2 system and see why it won't work on my car anymore? The scanner tool powers up just fine but I am not getting a link to the system.
No difficulty in starting. The car runs perfectly! If it weren't for the CEL light I wouldn't even know there was a problem. I do have the rotten eggs smell so it could possibly be an exhaust leak causing the problem? I'll be putting it up on supports tomorrow and having a look underneath.
