Question about 1994 Toyota Pickup
Put a jumper wire between the bottom two wires on the plug for the throttle position sensor, if it idles fine then the tps needs to be replaced. If that doesn't make it idle correctly, it could be one of the two water sensors on the left side of the front of the engine. If one of those goes bad it can cause it to idle up and down, just not sure exacly which one of the two causes it.
