start car with cap off let it run and see if air bubbles come out or if the prestone shoots up , if there is no heat coming out in the car possible heater core plugged have to clean it out or thermostat stuck as well cap leaks thats why no heat no pressure or leaking system check for prestone loss
Mid way is ok, but u need check thermostat, cheap to replace, also check rad is not blocked with insects, oil ok? Water cap tight? Turn on heat full in car see the temp drop, water pump can be on way out
First try replacing air filter if not done recently $30, next consider bad fuel put in fuel from major oil company from station with many patrons.Then you need to look at fuel delivery system including fuel filter and furl pump. But first try the 2 things mentioned.
Before getting too upset about this, try changing the temperature sender. Can't tell you where it is but it is usually on or near the thermostat housing but some engines have it on the intake manifold or rear of cyl head.
I DONT KNOW THE CODES OFF THE TOP OF MY HEAD BUT IT SOUNDS LIKE YOU HAVE AN EXHAUST LEAK AT THE FRONT OF THE EXHAUST SYSTEM AND THE OXYGEN SENSORS DONT KNOW ABOUT IT .IN TURN THEY ARE ADDING MORE FUEL TO YOUR SYSTEM BECAUSE TOO MUCH AIR IS GETTING SUCKED IN TO THE EXHAUST.
if you got heat when its running and almost nothing iddling the heater core inside the car has rectriction idle circulation not enough prestone pass thrue the radiator because of scale when our driving way more circulation more prestone go thrue ¸=more heat you need to flush the radiator inside the car normally i put a radiator flush leave it running longer then what they say go for a drive remove the heater core hose be carefull not to break the pipe use garden hose pass hose water pressure o n both side do it a few time each side flush all the prestone add new prestone you shoul have way more heat good luck p.s some shop might tell you change the heater core that perfect but very big money do it right its cheap and gonna work pierre
Mine (quest) would do this at 80 miles per hour with loaded car. Since I keep it at 72, it has not reoccurred. I suggest that the sensor is working fine. There is just a slight engineering problem with my engine that does not produce heat/vibration beyond the calibration of my sensor, as long as I keep the speed down. Fewer traffic tickets also.
