i was first getting p0172. Changed the MAF, ect sensor, and o2 sensors banks 1 & 2, both upstream.

Now I'm getting P0175. What now? I keep finding bank 2, but is it sensor 1 or 2? Should I look elsewhere for a fix? Any advice is greatly appreciate. I feel like I'd be better off pushing this damn car off a cliff.

The car is an '04 Is300.

 

Coolant temperature sensor. Saying the engine is colder than it is. So the computer says to rich the fuel mixture. The engine is much hotter . So after the fuel burns the o2 sensor says hey your to rich.

 

Hats the ECT sensor. I've all ready changed it.
