Just wanted to give a final update on this issue. It has stayed gone.... I still can't 100% point to a solution, maybe several things as stated earlier. She is still pulling timing but not at the same level as before. I tried a few different gas stations. And the 93 Esso had the worst KR (Weird since it's a really busy one), with the best being a Petro Canada 94 station. WOT HP fuel stays above 1800 PSI at all times, KR on the 94 Petro doesn't see above 3.0. I just wish I knew for sure what the issue was. One more mention that all the Gas in my area at least above 91 has 10% corn.
