Well I swapped in 4 brand new coil packs yesterday, and unfortunately the issue still persists..
Drove it last night after replacing the coil packs, and everything seemed fine. Drove for like 45 minutes or so and the car was great, however I never turned it off during that process. Idled perfectly, drove fine, pulled fine.
Today I took the car to the gym (20 min drive) and it was perfect all the way there. Car sat for about 90 minutes, came out and started it up. Idled fine, but as I went to pull out of the parking lot, I had zero to little throttle response, once again as if in limp mode. I was able to shut it off, let it sit for a bit, and drive for maybe 5 minutes before the throttle response completely disappeared once again. This happened to me roughly 3 times on the way home, and I was almost to the point of calling a tow truck but I was able to get her home.
Car did not want to idle properly after this happened a few times, and would idle very poorly/die, but I was able to hold it at ~2k rpm and just go, and I got home. Definitely leads me to believe its some sort of fueling issue, but it still doesn't explain why it would drive fine and then only do this after sitting for some time. One thing to note, I use the torque app to read boost/afr (I know its not nearly as good as a dedicated/hard-wired gauge) and occasionally my boost gauge would shoot up to like 25 psi, as if over-boosting or something, but I definitely never felt such a surge in power at all. The vacuum/boost gauge would also randomly stop working for some time, and then re-appear as well.
I don't know if this could be some sort of sensor gone bad.. maybe fuel pressure sensor or something, honestly not sure anymore. Thought perhaps a bad injector but the car is fine sometimes, and awful at others. If anyone possibly has any other ideas to try or check out I'm all ears, but also don't have the cash to really just be buying random parts in hope that they fix the issue so idk. This issue just sucks
