Why do Subarus take so long to warm up?
Newer Subarus have electronic fuel injection systems that are smart enough to know when the engine is cold and stay open for longer to give more fuel until the engine warms up. Once it does, the injection system adjusts and uses less fuel to keep the engine running.
Why does my Subaru heater stay warm in cold weather?
Since it takes a little while to go from cold to warm it might be that the engine warms up and the hot water is circulating though the heater core. That’s why it stays warm when you stop for awhile at a store etc. because the engine retains the heat, especially in warm weather….
What happens when the AC is on in a Subaru?
Check to make sure your cooling fans on the radiator are running when the AC is on. Check to make sure your cooling fans on the radiator are running when the AC is on. Click to expand… yea, both fans are running fine. Engine temp stays normal. Start with the obvious: Once the AC reaches the desired temperature, it’ll stop cooling.
Why does my Subaru Impreza stall when cold?
It starts just fine and idles smoothly when cold. It also drives good, great in fact when the engine is still cold – it accelerates smoothly and with plenty of power, but the second the temp gauge starts to move it begins idling rough, missing and loping and now it will even stall out and become very difficult to restart.
Why is the fuel pump not working in my Subaru?
Corrosion is resistance. loose pins at the plugs mean sporadic outputs or operation. Check them. Fuel pump could be running great and supplying sufficient fuel a for cold running engine and then as it heats up, with the engine, expansion of the metals in the pump or module reduces the pump output.
Why is my Subaru Outback having trouble starting?
I love my Subaru Outback 2007 but recently its been having trouble starting in the morning either when it’s cold or the temperature has changed significantly overnight. I recently moved to Louisiana so we’re not talking extreme cold, just cold for here. 50/40 degree weather.
Why does my Subaru a / C blow cold and then warm?
If I turn it off to go into a store or something, it’ll still blow warm, only gets cold again if it’s off for a while. It’s a 2015 with 88k and I’m out here in the desert of SOCAL, I thought maybe it running low on Freon, so hooked up the can of ac fix but the gauge displayed good pressure right away To rule that out.

Why is my Subaru running slow when I turn the key?
Fuel injection is designed to hold fuel pressure while the car is parked and this allows an instant start when the key is turned. If pressure leaks off (leaking injector, fuel pressure regulator, or the more common fuel pump check valve) the engine will be slow to start and may run rough for a minute.
