Why does my 1993 4-runner 3.0 v6 have hardly no power from 0 to about 40 mph also the check eng light is setting a knock sensor code?
Once the knock sensor is set on the computer tells the fuel injectors to only go to about 60 percent. Or half depending on who you talk to. Check cables and connections first. If these are OK then get another sensor from a wrecking yard and connect it without removing the old one. Then tie it down tight to the intake manifold. Run the engine again and see if the issue goes away. Then decide if you are going to get in the engine and replace the sensor.
