I asked the technician what would cause it to fail, and he said he did not know. In 2022 I bought it to get smog test and at that time they said my truck was equipped with the wrong catalytic converter. I was able to get a CARB Executive Order for the catalytic converter showing it is approved for my truck. I had to go through the BAR Referee to get the documentation. Now that it is not passing the smog test, I don't know what to do. A new catalytic converter costs almost $600. I do not want to spend the money if it is not what is causing the failure. The truck is running good. It had a high idle about a month ago, but I adjusted the timing and now it is correct. I replaced the distributor cap, rotor, spark plug wires and plugs approximately 3 months ago (3,000 miles ago) I changed the oil last month and replaced the air filter. I do not know what more I should do at this point. What could I check? I have been told Catclean is a good product to put in the fuel to clean things out. I have to get my fuel down to 1/8 of a tank and my tank is almost full, so it's going to be a few days until I am able to put it in my fuel tank. Any assistance is greatly appreciated. Thank you in advance.
