Okay so...latest development. Now the P2098 code is back and P0306 and P0316 have decided to join the party. Ugh.
We drove the car for a little over 4 hours round trip to Orlando to pick the cargo cover up (ran fine, although I thought it was idling a bit roughly), parked it, I took it around back to our alley to clean the wheels and when I went to move it back the CEL was back on and these were the codes that came up. P0306 says it is high risk and to not drive the vehicle if the light is flashing (it isn't).
Interesting thing is we filled the gas tank at the same station we had previously when the light came on. We tried different gas after the CEL was on the first time and it turned off. Octane is 93 at both stations, one is Shell (bad) and the other Wawa (good).
I'm at a loss here. Anyone?
