Heater not working when car is idle.
I posted this here because guys without FI dont usually have the same issues that us FI guys have. Usually a thing like this happens because of an FI kit.
Ok. it got into the low 50's tonight. This is the first time i've had to use my heater in a LONG time. actually my entire ac hasnt been working right because of a torn white ribbon behind the AC controls. I got that working fine now but when my car is at a stand still the heater will blow cold air. When i start to go again it turns hot QUICK. any reason behind this ? thanks guys.

shouldnt be air in the system, i havent taken off any coolant lines for air to get in. any way to check the thermostat ? it's no big deal really, just curious as to what it could be. dont use the heater much anyway, and if i do use it im usually not stopping much in the car.

When the rpm's are low the coolant does not circulate through the heater core very well at all.....my Maxima did the same thing. Just bring up the rpm's when you are sitting at a light.

Same thing happened to me last weekend. Changed coolant out and after refill the heater would blow cold air when I was at a stoplight and hot when car was in motion. Just needed to bleed the air out of the coolant lines. Problem solved.

Try idling you car for several minutes. If you see your engine temp go up (esp. further than normal), you probably have a coolant flow problem. A coolant line or your heater core could be partially blocked, or your thermostat or water pump could be bad. Any of these things should be fixed quickly, especially on a FI car, because of the heat issues.
If your engine doesn't heat up at idle, then the problem is limited to your heater only. If you can live with it, just ignore it.
I had a water pump go bad on a Mercury Sable I used to have. The impellar blades got chewed up, and spread throughout the cooling system, clogging the radiator, thermostat, and heating core. Major pain in the ***.

Like MIAPLAYA said could be air, if not your thermostat is dying. Make sure you watch your guage cuz your engine will get to hot and throw codes then shut down. This is a problem with being FI. I've gone through 3 thermostats and Im on my 4th, i may do like Mia and not run one. It doesn't get to cold here and my car is always warm....

I have the same problem; it only produces heat passed 3k.
We've bled the system like 4 times with the same result, I had a Nismo low temp. Thermostat installed about a year ago when I did my engine build.
Could the barely one year old Nismo thermostat be at fault?
I don’t drive my car in winter but want it fixed just the same.
I think I'll just buy a new Nismo one and see I it gets better.

Dont get the NISMO.
Here's what i did. I had my stock one on until 28k Miles when I went turbo.
Part of my build was the Nismo Thermo.
It lasted for about 10K miles and failed.
So I went with another. Then that failed very shortly after.
So I went with a stock one and that has lasted for a while however i got the damn cold heater thing. I wonder why they keep failing, its not rocket science its a damn spring that opens at a certain temp. geez.

Okay, so getting another Nismo is out.
I guess I'll put the stock one back on.Is Nismo the only option other than stock ?
