The car goes normal for 10 minutes of drive. After 10 minutes, the temperature gauges drops down near the bottom, then keeps go up to the center and back down. This results in idling problem from being at 700rpm when the gauge in the middle to 1500rpm when the gauge is near the bottom.
Change of the thermostat but didn’t fix the problem. I also have P0171 code, and changed O2 sensors, MAF sensors, still the engine light on. Any idea what would be the problem? Sometimes it works fine. Other times it’s a problem. Gas consumption is bad! Is it ECU? Electrical wiring problem? Fuses?
Also, I have a common problem with the remote. When it is hot outside, the remote only open the driver side door, when it cools down, it works fine! I don’t think this is a Toyota quality!
