What can cause fuel trims to not work sometimes?
This has happened a couple times while I have been logging. For some reason my fuel trim for one of the banks is at 0, causing my car to run very lean while WOT. Then instantly, the car will recover and fix the fuel trim. See log posted below. This was on a 3rd-4th gear pull. I have also seen this happen at the dragstrip. It happens sporadically, most of the time its fine though. I had some dragstrip passes the same night as the log below and they looked fine. What are your thoughts?
