  1. Adding subwoofer caused mass misfire on all cylinders

    Okay I'll try that aswell then, hopefully it is that simple of a fix
  2. Adding subwoofer caused mass misfire on all cylinders

    Okay I gotcha, yeah I'll have to try doing something else with the remote and seeing if that might fix it. I thought it was a battery/ alternator issue since my voltage while running sometimes goes as low as 12.1, that's with the amp and sub out of the car. With it in it went into the 11s sometimes
  3. Adding subwoofer caused mass misfire on all cylinders

    I did not, it happened with the old battery and the old system though. I honestly didn't know that there was a bms reset until recently, it's been a good bit since I put the new battery in, should I still go ahead and do the reset?
  4. Adding subwoofer caused mass misfire on all cylinders

    It's possible, I've seen other people use the back up camera as a remote wire with no issues but I can't think of anything else that would be messing with the car like it was
  5. Adding subwoofer caused mass misfire on all cylinders

    So I took out everything already, but the ground for the amp was bolted to bare metal I shaved the paint off in the spare tire compartment
  6. Adding subwoofer caused mass misfire on all cylinders

    Yeah the amp would turn off when the car isnt running due to the remote wire being tapped into the back up camera
  7. Adding subwoofer caused mass misfire on all cylinders

    Yeah, I'm not sure what was causing the problem. When I removed the amp from the car though the issues went away.
  8. Adding subwoofer caused mass misfire on all cylinders

    That would be interesting, I did have another sub woofer and amp setup in the car and it did cause the same problems though
  9. Adding subwoofer caused mass misfire on all cylinders

    I did have to replace the battery right before I put in the sub, But ive checked it a couple times to see what it was resting at and it seemed okay
  10. Adding subwoofer caused mass misfire on all cylinders

    it was happening even with the audio off, just at random times. 4 gauge power and ground and the amp is a single channel 800watt rms
  11. Adding subwoofer caused mass misfire on all cylinders

    I got you, would a capacitor make it to where I wouldn't need to upgrade the alternator?
  12. Adding subwoofer caused mass misfire on all cylinders

    Hi everyone, I have a 2015 gt premium with 70k miles on her. A few months ago i added a subwoofer to the car and then started experiencing weird misfires. when i would go WOT from time to time it would throw a flashing CEL and the codes would be misfires on everything. I chased it down and...

  14. -2.1 negative camber on stock suspension

    I'll go through it again and measure, I thought about putting camber bolts in but I didn't want to if I didn't have to
  15. -2.1 negative camber on stock suspension

    Okay I can try that this weekend, do you think the paper from the shop is wrong?
  16. -2.1 negative camber on stock suspension

    Hey I just recently got an alignment done on my 2015 mustang gt with 69k miles after getting new wheels and tires put on it, the only weird thing i have on it is the springs for the front and rear are off of a 2019 pp mustang gt everything else is stock and original to the car. Ive visually...
  17. Flashing check engine light multiple misfire codes

    I was also thinking something might be wrong with the cats and was planning on just installing bluetooth cats lol
  18. Flashing check engine light multiple misfire codes

    Yeah that is odd, I think I was able to fix mine fingers crossed. My voltage would drop down to like 10.3 cruising and I think my sub was pulling too much power causing my misfires. I've sinced removed the amp and sub and i haven't had it throw any codes but my idle is still kinda rough imo
  19. Replaced EVAP purge valve 3 times in 10k miles
