    HELP>>>>I have a 99 with a v6 and it runs lousy intermittently. This has very poor power and check engine light will come on and sometimes flash. I have checked codes and they are 300, 302,306. I have changed the plugs and coils. I have also found water in the air box every time I take it off. Sometimes this will run great and than it will run real bad.

    If you've changed the plugs and coils, then it's probably bad fuel injectors on cylinders 2 and 6. About a month ago, I had error code P302 and was having poor engine power. I ended up replacing the fuel injector on cylinder 2. It's been running great ever since.
