Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect Throttle Position Sensor (TPS)

Locate the TPS on the throttle body.
Disconnect the electrical connector from the TPS.
Use a multimeter to check the resistance across the TPS terminals. Compare readings to manufacturer specifications.
If the TPS is faulty, proceed to replace it:
- Remove the screws securing the TPS.
- Install the new TPS and torque to manufacturer specifications.

3. Check and Replace Transmission Fluid

Locate the transmission dipstick and remove it to check the fluid level.
If the fluid is low or burnt, drain the old fluid:
- Place a drain pan beneath the transmission pan.
- Remove the transmission pan bolts and carefully drain the fluid.
- Replace the filter if necessary.
- Refill with the appropriate transmission fluid based on manufacturer specifications.

4. Inspect and Adjust Accelerator Pedal Linkage

Check for any obstructions or binding in the accelerator pedal assembly.
If binding is found, lubricate the linkage with appropriate lubricant.
Adjust the throttle cable if necessary to ensure it has the correct tension and travel.
