Here's why you should not attempt to repair this issue yourself:
* Safety Risks: Working on a car engine requires specific knowledge, tools, and safety precautions. You risk serious injury if you don't know what you're doing.
* Complexity of the Issue: Diagnosing a stuck valve or faulty valve springs can be complex. It may involve removing the cylinder head, inspecting valves, and potentially replacing parts.
* Potential for Further Damage: If you attempt to repair the engine without proper knowledge, you could make the problem worse and cause more expensive damage.
Instead, here's what you should do:
1. Find a reputable mechanic: Look for a mechanic with experience working on Chevy Malibus or similar vehicles.
2. Describe the symptoms: Explain the rough running, possible stuck valve, and any other noises or problems you're experiencing.
3. Get a diagnosis: The mechanic will need to inspect the engine and determine the exact cause of the problem.
4. Get a repair estimate: Once the mechanic has diagnosed the issue, they can provide an estimate for the cost of repairs.
Remember, it's always best to trust a professional mechanic to handle serious engine problems.
