2024 Civic Sport Touring 6MT
Hello all! I'm coming here from CivicX after having some issues with my 24 Civic Sport Touring MT.

Dating back a couple weeks ago I ran into an issue where my gas pedal suddenly just stopped working mid drive, it began working after a second or two but it was out of the blue. At this point I was tuned using KTuners Starter 21 Dual tune, but ran TSP Stage 1 before with zero issues. (This comes into play later) I immediately pulled over and began trying to replicate it, but it is hard to replicate. After a couple minutes it happened again and I decided to flash back to Stock Tune to see what would happen and to my surprise it happened again. In total it happened 3-4 times and having only 22,000 I brushed it off.

Fast forward to yesterday, it happened again. This time I was on the TSP Stage 1 Tune. I was able to capture two data logs where this happened, although I am unable to pinpoint exact timestamps in the log of when it happened. In the first log, somewhere between the 2-3:30 mark it happened a couple times and in the second log i believe it was happening fairly consistently up until the last 30 seconds. My best guess is that in my quick adjustments I had the monitor for P0299 enabled (underboost), which would throw my car into limp mode (dead gas pedal) so I disabled the monitor and have been good so far but only drove maybe 5 miles. I may be completely off, and to be honest I wouldn't be shocked as this has been very confusing. To get the pedal to work again, I learned that pushing in the clutch resolves it, as well as shifting but if I keep pushing the gas pedal nothing happens.

I emailed TSP and they are looking into it, but I would love to know if anyone else has experienced similar or has any input. I've done very little to my car (CAI, Catback Exhaust, Tuner) and do not believe anything is mechanically wrong. The only other issues I have been having would be sometimes losing break hold due to errors such as "Parking Brake System, Collision Mitigation System, Brake Hold System, Brake Performance, Forward Collision Warning) however I assume it is likely a dirty sensor as I live in Upstate NY and the weather is... quite difficult to say the least.

UPDATE: Here are the datalogs
