Was out on a road trip and the MIL came on on my 96 XLT (V8). Also I noticed that it idles rough now, which I assume is related.
Scanned the computer and came up with 1150 Lack of H02S21 Switch Adaptive fuel at limit. AND 0174 Bank 2 lean.
This happened shortly after filling up at a cheapo gas station, so I'm wondering if it could be caused by bad fuel. ?? I cleaned the MAF and throttle body and replaced the fuel filter since it was overdue anyway !
Not sure where to go with it, but I thought I would tank up with some known quality gas, and run it a while to see what happens...
Any thoughts ?
thanks.
