as for the rpms. that's a vac leak somewhere. spray starter fluid around the injectors and lim to see if the rpms fluctuate.
Thanks i'll do that so as far as the low coolant situation just replace coolant with the car on? I know white smoke is gonna come out but it needs to be filled up Engine coolant temperature sensor code comes on too after I replaced it with a new one might be a bad LIM or something... idk but I have a gen v lim im putting on when I do the swap as far as vac leak/sound Its by the throttle body/intake but I will be swapping throttle body's as well
