so was doing a highway pull as you normally do and around 4,000rpm something went wrong, nothing was blown up and no fluids came out, but now the car doesn't idle properly, fluctuates between 300-1,200rpm and if you press the gas it'll rev to about 2,000 and then proceed to stall, even with foot still on gas, put it in drive and it'll idle at 300-600 for a couple seconds then stall, basically it doesn't move anymore, i have no idea what could've happened as im new to all this and nothing (at least externally noticeable) was busted. any assistance and suggestions are welcome, please help ! lol
