Codes, Fuel and EOS

Recommended Posts

My '97 is running eye-wateringly rich. I don't mind too much - I didn't buy the car for its fuel economy. 😀  But it does make it hard to start. I am wondering if these are common issues with common fixes. If not, I'll try to find some reference material, but maybe you more experiences owners will say "oh, yeah - adjust this replace that. Quite common on these cars."

Here's my list:

P0172 System Too Rich Bank 1
P1301 No description available
P0175 System Too Rich Bank 2
P0141 O2 Sensor Heater Circuit Bank 1 Sensor 2
P0133 O2 Sensor Circuit Slow Response Bank 1 Sensor 1 P0161 O2 Sensor Heater Circuit Bank 2 Sensor 2

P1301 is a misfire code related to increased emissions.

When were your O2 sensors replaced last?  Faulty or failing sensors will result in those codes.

If they have been replaced recently, I would check for connections or part compatibility.

If they are older, then I would consider replacing them and resetting the ECU.
