  1. It's a good idea to check fuel trims and o2 operation. Wouldn't want the inferior aftermarket to fail quickly. Wouldn't be a bad idea to replace o2 sensors if they have a lot of miles on them plus after you crack them loose they usually crap out.

  2. I know you made this video years ago but it just helped me replace the manifold in my RAV4 because I don’t have the money to pay a professional, so thank you!
