I don't. The island is on the opposite side of the station. I was thinking the gas station fucked up.
Went back to 91 and haven't thrown any codes. After 20 miles, my LTFT during partial throttle is 10-17% below 4500 rpm and then 3% above 4500 rpm (partial throttle). I didn't do any WOT pulls. I'll do some tomorrow and log it.
The good news: no codes, IAM stays at 1
Bad news: LTFT is 10-20% in the lower rpms, but drops below 5% in higher rpms.
