Current odometer 216,xxx

Recently got the p0304 code. After thorough investigation (coil packs, wires, gaskets etc) the injector was the issue. p0304 code is cleared.

Immediately after the fix I drive around and a P0300 Random misfire code si thrown, that was not thrown before. I carefully pull everything apart and put it back together.

Now it runs still with a misfire, however no codes will show after driving around.

1800 rpm and 40mph is a happy place for then engine. It runs smooth as if there was no issue.

Thoughts advice ???????

Engine? Vehicle?

I'm assuming 3.4 V6 in your 97 runner

Very first thing I would do is check grounds...at least one I can think of was unbolted to replace an injector
