well after driving it home, there were 11 DTCs.

P1125 LTFT Add. Air B2 too rich
P1126 LTFT Add. Air B2 too lean
Fuel Sys 1 Closed Loop
Fuel Sys 2 Closed Loop
Calc. Load 26%
ECT 183deg F
STFT B1 25%
LTFT B1 28.9%
STFT B2 25%
LTFT B2 28.1%
RPM 2840
Speed 72mph

P1128 LTFT Mult. Air B1 too lean
P1130 LTFT Mult. Air B2 too lean

P1132 O2 S1 B1&B2 control signal too high
P1133 O2 S1 B1&B2 control signal too low

and DTCs for multiple misfires.

those fuel trim numbers are at max enrichment.

so after a lot of reading, i'm thinking the MAF crapped out. cleaned it and reset the codes. will find out in the morning (not starting it at 3am).
