13- Oxygen sensor signal fault-signal too low / open left oxygen sensor circuit (Dual sensor models)
12-Diagnostic mode; no distributor signal to Electronic Control Module; System PASS
21-Throttle position sensor (TPS) - signal voltage to high
35-Idle air control (IAC) system problems - can not set desired RPM or idle speed actuator (ISA) carbureted system problems
45-Rich exhaust indicated (Left side on dual oxygen models)
So you have 2 O2 codes, 1 of which is rich like I called it. . . What's really boggling my mind is why you'd set foot through the door of the smog ref with all those known issues then ask for help and not lead with the codes?
