Hey there, Scott!
So, you're getting the P0420 code on your 2013 Ford F-150 3.5L Ecoboost. That usually means your catalytic converter isn't working as efficiently as it should. Here are some cheap DIY solutions you might want to try before taking it to a mechanic:
1.) Catalytic Converter Cleaner: Pour a cleaner into your gas tank and run the engine for a bit. It might help clear out any blockages in the converter. This is a pretty cheap option, around $10-$20.
2.) Clean the Catalytic Converter: If the cleaner doesn't work, you can try removing the converter and soaking it in a bucket of water and detergent for about 10 hours. This method is free if you already have the materials, but it's a bit more involved.
3.) Check the Oxygen Sensors: Sometimes, a faulty oxygen sensor can trigger this code. Replacing it might fix the issue. Sensors are around $50-$100.
4.) Fuel & Ignition Tune-Up: Bad plugs, dirty injectors, or a clogged air filter can cause excess fuel, hurting the cat. If you haven’t done a tune-up recently, it’s worth trying. It would cost $150–$500, depending on whether you DIY or go to a shop.
If none of these work, it might be time to replace the catalytic converter, which can be pricey. But before you do that, make sure you've checked for any other issues like exhaust leaks or faulty spark plugs.
Remember, if you're not comfortable with DIY repairs, it's always best to consult a professional mechanic.
