Q: How to disconnect and reconnect the throttle valve cable and related components on Toyota MR2?
A: Disconnect the cable from the negative terminal of the battery, then disconnect the throttle cable housing from the bracket and the cable from the throttle linkage and clamps. Remove the neutral start switch and the oil pan, followed by the two bolts and the apply tube bracket. Take out the three oil strainer mounting bolts and the oil strainer, noting that some oil will come out during this process. Unplug the solenoid connectors, pry up the tube ends with a large screwdriver, and remove the oil tubes. Remove the manual detent spring, the manual valve, and valve body, then take out the valve body mounting bolts and pull the valve body away from the transaxle while disconnecting the throttle cable. Remove the bolt and retaining plate to pull the cable out of the transaxle case, then install the throttle cable in the transaxle case, ensuring it is pushed in all the way, and install the retaining plate and bolt. Install the second brake apply gasket while holding the cam down, slip the cable end into the slot, and position the valve body carefully to avoid entangling the solenoid wires. Finger tighten the valve body bolts before tightening them to the specified torque, ensuring not to mix up the bolts. Connect the solenoid wiring, aligning the manual valve with the pin on the manual shift lever, and place the manual valve and body in position. Finger tighten the four bolts first, then tighten them to the specified torque, ensuring not to mix up the bolts. Install the detent spring, finger tightening both bolts first before using a torque wrench, ensuring the manual valve lever is in contact with the center of the roller at the tip of the detent spring. Install the oil tubes by tapping them into position with a plastic hammer, being careful not to bend or damage them, then install the apply tube bracket and the oil strainer, tightening each bolt to the specified torque. If the throttle cable is new, bend it to create a radius of about 200 mm (7.87 in), pull the inner cable lightly until slight resistance is felt, and hold it. Stake the stopper 0.8 to 1.5 mm (0.031 to 0.059 in) from the outer cable, connect the throttle cable to the throttle linkage, the cable housing to the bracket, and the cable to the clamps. Adjust the throttle cable, install the neutral start switch, connect the transaxle control cable, and finally, test drive the vehicle.
