Hey ive been having this problem for a awhile now ive checked literally everything. IACV is fine and cleaned, my car doesnt have a FICV so thats out. Ive burped my coolant twice so it aint that. i did fix it ig my Mom didnt put on my radiator cap on right so that was the problem i so thought. it did fix for like maybe a month. i recently installed a SUB wit amp Obvi, the amp is 1100 WAT if that helps. i unplugged it and it was still doing it so IDK what it could be. heres a video of whats happening. Before i took a vid when i hold the idle at 2 flat it would like move up and down and wont stay consistent when i apply gas but in the video it doesnt do it literally stopped. i was thinking maybe sumthing fuel related since its like jerky in low RPMS like around 2k i try to apply gas it would just jerk. no vid on that. i aint a Mechanic so i cant even find out whats happening ***** so annoying that i be the only 1 with random *** problems no 1 else got lmao
