Yes it shifted to second gear. What I noticed is that whenever I try to push the car now above 4k rpm with full throttle, the car seems to choke, So Its propably its a fuel issue (ether hpfp or injectors) but I'm gonna have my coils tested too. (I had my spark plugs changed 10k miles ago)
Yeah It shifted, the mechanic gave me an appointment scheduled to tomorrow since he had too many customers.. so luckily I'll update you guys tomorrow.

Turning the car off def made it go back to normal, but if I punched it, I would get the same exact problem. I changed the ignition coils and spark plugs and the issue went away. You may only need to change the spark plugs, but Im at 80k and drive like a maniac, so I changed both lol

Thanks for your input, I changed my spark plugs 10k miles ago, right now I'm suspecting HPFP/injectors since its choking when I give full throttle, but I'll have my coils tested too.

kifak man? b3atle PM w bse3dak to debug  |
That's what I'm doing, Im driving slowly and not exceeding 2.5k rpm. Ana mnih bro but I dont have jb4 or scanner to read the codes, I'm going tomorow to a mechanic w hopefully he'll get it sorted.. Thanks for your help bro appreciate it

did you have it fully off (hold for 3 sec) or just DTC (single press) ?

Yeah I know usually I would troggle DTC off (single press) and i press on the gas and like you said, the traction control cuts power abruptly and it would make a bang too.
However, what happened yesterday wasen't normal at all. I had it fully off (3sec) and it made 3 huge bangs very similar to a subaru antilag or 2step (RAPAPAP <- like that) while shifting to second gear after hitting the redline.

Yeah I'm currently suspecting ether HPFP or injectors. And no its not gone haha my car chokes wherever I give full throttle above 3k rpm

That's what I did, drove it slowly and kept rpm needle under 2.5k. Going to the mechanic tomorow to read codes/get repaired.. well keep u updated, thanks for your input..

Yeah Im suspecting primarily HPFP/Injectors and secondarily the coils.. Im going to the mechanic tomorow so we'll see.. Thanks for your input, will let you know if it was my coils or not.
