OBD1 - 147 and 327 codes
(1993 sable 3.8)
mil light went on, some rough idle and then everything is ok and now the light is off - I pulled the codes anyway, since I do have an ongoing problem that's different than this. The codes I got are:
157 MAF sensor circuit open.
327 PFE sensor circuit voltage below Self-Test minimum.
The other problem that I have had for a long time is that when I go down a long hill on the highway, the mil goes on, but once I start accelerating again on flat ground it goes right off. I don't know if these codes are related.
Any help appreciated!
