Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover (if applicable) using a socket set.
2. Disconnect ignition coils and remove them from the spark plugs.
3. Use a spark plug socket to remove and inspect spark plugs for wear or damage.
4. Replace with OEM-spec spark plugs, ensuring the correct gap is set.
5. Reinstall ignition coils and reconnect them.

3. Fuel System Inspection

Sub-steps:
1. Locate the fuel filter and check for clogs; replace if necessary.
2. Use a fuel pressure gauge to check the fuel pump's output; replace the pump if pressure is below specifications.
3. Clean or replace any clogged fuel injectors using a fuel injector cleaning kit.

4. Transmission Fluid Check and Change

Sub-steps:
1. Check the transmission fluid level using the dipstick; add fluid if low.
2. If fluid is burnt or discolored, drain and replace with the manufacturer-recommended fluid.
3. Reinstall the drain plug and refill the transmission with new fluid.

5. Throttle Position Sensor (TPS) Testing

Sub-steps:
1. Disconnect the TPS connector and use a multimeter to test the resistance across the terminals.
2. Compare readings to specifications; if out of range, replace the TPS.
3. Reconnect the TPS and reset the ECU by disconnecting the battery for 10 minutes.
