So I just bought a 96 integra LS with a b18b1 5peed. I installed a stereo but had an issue with it, was a bad ground, and fixed it with grounding it out somewhere under the dash. The next day I went to race a friend and when under wide open throttle the car started to sputter, the lights on the dash came on, the stereo reset, and headlights dimmed(all on). And so I let off and kinda limped home. The car sputtered a couple times and the stereo reset a few times. But when I shut it off(stereo) I did a 1st/2nd pull and it felt fine. What could this be?
