Q: The temperature gauge is low and the engine does not get enough power

I love to drive, especially with living by the beach in Southern California, but I know first hand that it's not fun to drive when you're not able to get comfortable in your own car seat. It can be quite...

If your vehicle is designed to be a flexible fuel vehicle (not all are), you may encounter some problems starting the engine in very cold weather. This is particularly true if you’re running E85. Here’s what you should know: Crank...

I would recommend having a qualified professional come and perform a cooling system pressure test (https://www.yourmechanic.com/services/coolant-is-leaking-inspection) on your vehicle. There are many places on a vehicle where coolant can leak from, including the hoses, radiator, water pump, and heater core...

Hello. If all of these parts have been replaced and the problem persists, then you either have a bent wheel hub or there is a worn out engine mount (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-engine-mount). Both of these will cause this. I usually check the...

The shifting is controlled by the transmission control module and if the shift light is flashing then the module is detecting a problem in one of the sensors (like a speed sensor which will cause the module to set a...

Hello. The heater is a part of the vehicle's cooling system and uses the same fluid. The first thing I would do is check to make sure that the system is properly filled and bled. If any air gets trapped...

This may be related to a few different things such as a bad injector (https://www.yourmechanic.com/services/fuel-injector-replacement), fuel pressure issue, or potentially a faulty mass air flow sensor (https://www.yourmechanic.com/services/mass-airflow-sensor-replacement). A common symptom of a bad mass air flow sensor is very similar...

Hi there. The code P115D (http://www.obd-data.com/p115d.html) is for the mass air flow sensor (MAF (https://www.yourmechanic.com/services/mass-airflow-sensor-replacement)). It says that the sensor has an offset signal. The code P2178 (https://www.yourmechanic.com/article/p2178-obd-ii-trouble-code-system-too-rich-off-idle-bank-1-by-jay-safford) says that bank 1 is too rich. This means that the engine...

Hi There, If I understand your question correctly, the main problem is the operation of the blower motor and not the generating of heat from the heater core. If this is the case, it sounds like you have replaced all...
