Common causes include a faulty oxygen sensor, loose gas cap, bad catalytic converter, or issues with the spark plugs or ignition coils. An OBD-II scanner can be used to diagnose the specific issue.
Start by checking the AC fuse and relay, ensure the refrigerant level is adequate, inspect the compressor and belts, and look for any leaks in the system. If the problem persists, a professional diagnostic is recommended.
Signs include slipping gears, delayed or rough shifting, unusual noises like clunking or whining, and leaking transmission fluid. Address these issues promptly to avoid further damage.
To replace the cabin air filter, open the glove box, remove the retaining clips, lower the glove box door, and access the filter housing. Remove the old filter and insert a new one, ensuring it is oriented correctly.
Check for electrical components that may be left on, such as lights or accessories. Test the battery and alternator for proper operation. If the issue persists, inspect for parasitic drains or have a professional conduct a diagnostic.
To replace the brake pads, lift the vehicle, remove the wheels, detach the caliper, and remove the old pads. Install new pads, ensuring they are properly seated, and reassemble the components. Always check the brake fluid level and test for proper function.
