Thread: Trouble Code P0306

    I hear ya but with my luck if another one goes out it wouldnt have been the one I put the spare in. I also didn't want to risk a cheap replacement leaking or causing other troubles.

    I am curious what the ports look like at the end.
    Here is the business end. I couldn't get a picture of the 4 small holes inside of the pig nose especially when it's as dirty as the used injector. This is what 17 years of spraying fuel looks like.

    PCV looks fine and still has the check valve moving. It was one of the things I yanked on when I first got the code. The one on there isn't too old but I ordered a new one. I also need to change the fuel filter. I've been meaning to do it since I bought the 4Runner, almost 9 years ago.

    For reference here are my injectors and spark plugs when I pulled them out of my truck when I was having the back fire issue:


    I am trying to look through my other picks to remember which cyl each came out of.
    EDIT: In order from left to right 1 3 5 2 4 6

    In my case my injector wasn't fully closing instead of not opening and firing.

    I replaced the PCV gasket too, Mike. It looked fine, the PCV itself slipped in just fine, but when I removed it the thing cracked to pieces Luckily my years of playing Operation as a kid allowed me to pick it out with no problem
