Kavid, if you're coming to the meet tomorrow night, I can bring my scanner, and we can take a closer look. If it's the same code for the EGT, it's most likely that you'll end up needing to replace it, and then reset the ECU again.
I'll be sure to bring the scanner with me!
Resetting the ECU with a scanner, and clearing the "self learn" that I spoke of, means that the ECU is cleared of all of the monitor setting items, and the adjustments it makes to fuel/ignition timing, etc., according to the way you drive. Even when the light turns itself off, any adjustments or fail safes it's set to keep from damaging the engine due to the part failing don't reset themselves. It's gotta be done specifically with a scanner, which I'll be sure to throw in the car tomorrow, in case you can make it out!
