Okay so my at was missing really bad so I started pulling injectors to find which cylinder it was. It my driver side cylinder closest to the bumper. We test lighted it and it was getting randomn little surges of power. Ad the others would just light the test light up. And it had also made my check engine light flicker and short out. I don't know anything about electrical so please help me! Have any of you had this problem?

You're goingto need a multi meter or some one with one to do any further testing. I'd suggest checking that you have a good 12v at the injector with the key in the ON position and engine not running. Also, check the continuity from the injector to the ECU.
