1. Check for any immediate problems: Look out for any serious issues such as low oil pressure or overheating. If either of these problems or any other serious issues emerge, you should pull over and shut off your vehicle immediately. 2. Remain calm and examine the dashboard: Don't panic - an illuminate engine light doesn’t mean your car is about to explode. It’s often indicating that some component of your vehicle isn’t working as efficiently as it should be. 3. Keep track of your vehicle's performance: If it feels or behaves differently than normal, take note of it. This can be useful information for your mechanic. 4. Use a diagnostic scan tool: If you have one, use it to read the error code. If you don't, stores like Autozone will do this free of charge. 5. Visit a mechanic: The best course of action when your check engine light appears is to take your vehicle to a trusted professional to diagnose the problem. The mechanic will likely use a diagnostic scanner to read the error code, then interpret it to identify the issue. If possible, take the car to the mechanic when the light is still on. 6. Ask to see the problem: Before agreeing to any repairs, ask to see the faulty part if it's visible. A trusted auto repair shop shouldn’t have any problem showing you what’s wrong. 7. Fix the issue: Once you have an understanding of the problem, discuss the options for repair with your mechanic and decide on the most appropriate course of action. 8. Reset the check engine light: Once the issue is fixed, the check engine light should be reset. The mechanic should handle this, but if not, it can usually be done by disconnecting the battery for a few minutes. Remember that driving with the check engine light on isn’t a great idea. If the problem is serious, you may risk causing serious damage to your car by driving it.

Repairing or setting up engine timing requires technical knowledge about engines. If the engine timing is not correct, this might cause your vehicle's performance to decrease dramatically. Here is a general procedure: Materials: - Service manual - Timing light - Wrench Procedure: 1. Consult your vehicle's service manual to understand the type of engine timing your vehicle uses. Depending on your vehicle, it may utilize a distributor, a timing chain/belt, or it may have a distributor-less system that you need to be adjusted electronically. 2. Warm up the engine. The engine needs to be warm to ensure correct timing adjustment. Run your car for approximately 10 minutes in order for the engine to reach its normal operating temperature. 3. Locate and attach the timing light. Check your service manual to see where the ignition timing is located. Typically, the marks are on the harmonic balancer located on the crankshaft. The timing light needs to be clamped onto the number one spark plug wire and the power and ground leads attached to the correct battery terminals. 4. Check the timing. With the engine still running, aimed the timing light at the timing marks. Compare the measurement on the timing tab to the specification in your manual. 5. Adjust the timing if necessary. If the timing is not correct, loosen the distributor clamp bolt enough to allow slight rotation. Rotate the distributor until the right timing mark is hit, then tighten everything back down. 6. If you have a newer car with electronic timing, it will need to be adjusted by a mechanic unless you own the specific diagnostic and programming tools required for your car. 7. Once you are done, remove the timing light, replacement of any disconnected wires or moved parts, and shut down the engine. Remember, the procedure can vary largely depending on the vehicle make and model. Always refer to the service manual for best results. If you are unsure how to do it, it's better to take your vehicle to a professional mechanic who will do this for you. Disclaimer: Working on a vehicle engine can lead to severe injuries or damages if not done properly. It is recommended to hire a professional if you are inexperienced.
