My cousin has a 1997 Buick Lesabre. On Thursday his MIL came on and I
used a scanner to get the code. I don't remember exactly what it said but it
was something like the "O2 sensor, bank A, CKT" The auto store had me replace
the sensor and I cleared the codes and it was okay until today.
Today my cousin said it started to run rough for a few seconds and the MIL
came on. The codes I got are:
P0121: TPS/PEDEL POSITION SENSOR A CKT RANGE/PERF
P0121: PD (saa,pending)
P1406: AUXILIARY EMISSION CONTROLS MANUFACTURER CONTROL
I really feel bad for him. He's in his eighties and has had a lot of car
trouble. Does anyone have any ideas?
