These four codes came up after a loss of power. Not sure what was
the cause other than possibly bad fuel.

P1125 - Oxygen sensing adaptation, upper load range, cyl. 1 - 3
Short to ground / below lower limit / lean mixture threshold
Short to B+ / above upper limit / rich mixture threshold
P1126 - Oxygen sensing adaptation, lower load range, cyl. 1 - 3
Short to ground / below lower limit / lean mixture threshold
Short to B+ / above upper limit / rich mixture threshold
P1132 - Oxygen sensing adaptation, upper load range, cyl. 4 - 6
Short to ground / below lower limit / lean mixture threshold
Short to B+ / above upper limit / rich mixture threshold
P1133 - Oxygen sensing adaptation, lower load range, cyl. 4 - 6
Short to ground / below lower limit / lean mixture threshold
Short to B+ / above upper limit / rich mixture threshold
Would a failing fuel pump trigger any codes?
