Hello everyone, my vehicle GS300 2010 has been the target of loss of power and low on efficiency. it will drive around but its become poor in every aspect. To add to my worries i look it to the dealership last week and they could not find a single problem with the battery, engine, alternator/starter, sparks, wires, etc. I tried googling the problem since i am afraid its going to shut down completely soon and i cant afford that. Found a couple of problems related to "loss of power" and they mentioned something along the lines of a sensor that might have stopped working which is why the car might be performing so poorly. Can someone tell me in layman's terms which sensors we are talking about? Thanks
