92 Chevy S10
1992 Chevy S10 4.3L. Truck starts fine and idles ok. While driving it down the highway it wants
to spit and sputter so to speak only when I back off of the gas pedal a bit. Obviously this is OBD
1 and I didn't have a scan tool so I jumped the connection on the plug and counted flashes. I was
getting codes 13, 33 and 44. I changed the MAP sensor already and fixing to change the O2
sensor tomorrow. Would a bad O2 sensor cause this?
