Fuel injectors firing numbers

Hey Danny, so I was wondering something so I reset the CEL with the p0420 code and the code only comes back on during the night time when it is cooler. Keep in mind that during the day it is 105 plus degrees outside in Las Vegas. So is it possible that catalytic converter is not getting hot enough during the night? I did get the code p0128 and my temperature gauge never reaches the middle no matter how long I drive it.

Hi again.

No, temperature will have nothing to do to set the code. If you keep turning the CEL off during the operation of your car and all the data the vehicle is receiving from sensors/monitors when a component has failed the CEL with continually come back on. The code P0128 is the code regarding the thermostat we spoke of previously.

Hello again.

As stated in my prior post it was the right (passenger) converter. The price $450.00 is not too bad. My 1997 Silverado catalytic converters were $269.00 apiece installed (needed both within four years), but a customer of mine had the highest price I have ever seen $2,100.00 for a Ford Supercrew! Glad to hear your vehicle is coming together. Let me know if you have any further questions and thanks again for using 2CarPros.

Hello again, Danny here.

That code is your Upstream Bank 1 heated O2 sensor. Unfortunately it is my experience that it goes hand in hand with the bad catalytic converter on that side. Having that misfire damaged that sensor and converter over time. Usually O2 sensors run $60.00 to $90.00 from auto part stores but nowadays people like shopping online to save money. I am confident you can do this repair. Here is the tutorial for O2 sensors and location.. Danny-

That would be a good idea if they are worn/showing signs of needing replacement. Sometimes I do replacements when work is in a tough spot just knowing it is a bear to get to and not wanting to do it again soon for awhile. Let me know if you have any questions.

As we previously discuss I changed out the number one fuel injector and ever since I bought this car I had a strong smell of fuel by the intake manifold and then I can smell it in the cabin of the vehicle. Now from the picture that I uploaded do you think that o-ring is bad and would cause a fuel leak?

Hello again.

Well that will happen with age/wear. Since you have changed them there should be no more misfire! Did you complete the thermostat change?

Oh, I only changed one of fuel injectors.

I did not change the thermostat. I am going to buy radiators hoses and attempt to remove the thermostat.
