Hey Everyone,
So I have an issue. My car was running fine and then all of a sudden it seemed like my 1 of my coil packs just died. Here's exactly what happened.
Drove my car to work this morning fine (Roughly about a 30 minute drive and then before turning off my car, let it idle for about 2-3 minutes). Roughly about 9 hours later, I started up the car again. That's when the issue happened. Once I started it up, you could hear the problem. It sounded like a suby. Took the car for a small drive, no more than 2 miles and kept the RPM under 3K. Mostly between 1K-2.5K RPM because I didn't want to push it. The car shakes a bit at low speed/low RPM rev and had that suby sound all the way up to about 2.5K RPM. As I said, I didn't want to push it any further as something is already wrong. I don't see a need to try and push harder than what was needed to hear and feel it out.
I did recently have my plugs changed, and after the change, the car ran a lot smoother so I don't think the problem is related to my plugs. They're gapped at .8mm and are the copper type. $13 I believe was the cost of the plugs and the best damn $13 bucks I spent lol.
I lost coil packs before and it was a problem when I was trying to get my car tuned a long time ago. The tuner kept blowing coil packs (Specifically #6, the one closest to the firewall) and it would break up in the high RPMs. He was able to get it to a nice tune and I didn't run into any issues for quite some time until now. Since the car has sat for quite some time, I lost the tune we had. It was done through a Apexi SAFC. So my car should be running how it is stock. My boost is set to a good decent amount, but I have not boosted past 10 PSI since I got the car back up and running. I have also not revved past 5K RPM as well since I got it back up and running (within the last 2 weeks)
Does anyone know what the issue could be? The tuner suggested that it could be related to a wiring problem when I had the whole swap done a long time ago. He also suggested that I should consider upgrading coil packs as well but said he wasn't sure if it was such a good idea because if the issue is something else, I might end up blowing the new coils.
