Three DTC's, CEL is on

[kawboy]

0136 O2 Sensor Circuit Malfunction (Rear)

0141 O2 Sensor Heater Circuit Malfunction (Rear)

1400 Manifold Differential Pressure (MDP) Sensor Circuit Malfunction

Are the two O2's from having no cat? And about the last one, I guess my sensor is just dirty or bad. I have a 1g Intake Manifold on my 7 bolt, would that cause it? Also all my vacuum lines are gone I believe. Mods in profile

I'm trying to get somewhat closer to passing inspection, please help

Thanks

BTW, Can DSMlink display more than three DTCs at a time?

Alright so 1400 is showing because 1g's dont have a MDP sensor

The rest.. maybe I don't have a bung nor rear O2... I'll have to check

Is the second o2 sensor still there? Or did you cut it out?
