Engine Performance problem
2000 Toyota Prado 6 cyl Four Wheel Drive Automatic 180000 miles
Trc symbol with engine were started to show up in dash bord. They were not blinking. When car is started from stop, after 10minutes in to running the engine they come up on dash board and stay. As soo as they appear I can feel that enging started to slow down. Eventhough I accelerated car wouldn't raise. No pick up at all. When I checked the car. Scan reading was faulty knock sensors. Is this the problem? If it is where do they locate exactly?
