I think you dont have to drive the car right now because the cooling system might be the probleme causing the engine to be overheated and slow down the combution , i think u should check the radiator
Tune up
try 92 octane or higher.
Misfiring in a car when it is cold can be caused by several things. The mist likely causes are a bad head gasket or a leaky fuel injector. Either of these can allow fluids to slowly mix overnight and the car will misfire until the excess burns off.
Wait until it warms up and melts
while driving the car it warms up and becomes dependant on the maf sensor to run the car properly. when you first start the car it runs on a pre programmed set of parameters independent of sensor data until it gets to operational temperatures on various sensors (drive cycle) restarting your car resets the drive cycle temporarily
Most cars will idle high until the engine warms up. If your car continuosly runs high have the fuel system checked.
The heating system doesn't get heat until the car warms up and the thermostat opens.
EGR Valve
Bad ignition wires.
car start and drives fine bu when its turned off it wont start until it cools?
check the brake booster vacumme hose,its the hose than runs from the intake to the brake booster. if its leaking air the car stall when you hit the brakes or has no power
