Why did your Engine stall while driving also rotten egg smell 1999 daewoo leganza?

I understand you're experiencing a frustrating issue with your 1999 Daewoo Leganza - stalling and a rotten egg smell. It's important to note that I can't diagnose mechanical problems remotely, and a professional mechanic is the best resource for this. However, I can give you some possible causes and steps to consider:

Possible Causes:

* Catalytic Converter Failure: The rotten egg smell is a strong indicator of a failing catalytic converter. This component helps reduce harmful emissions, and when it malfunctions, it can release sulfur dioxide, which smells like rotten eggs. A failed catalytic converter can also lead to engine stalling, as it restricts exhaust flow.

* Fuel System Issues:

* Fuel Pump Failure: A failing fuel pump can cause the engine to stall, especially when accelerating or driving uphill. It might not deliver enough fuel to the engine.

* Fuel Filter Clogging: A clogged fuel filter restricts fuel flow, which can lead to engine stalling and poor performance.

* Fuel Injector Problems: Clogged or faulty fuel injectors can prevent proper fuel delivery, resulting in stalling and rough running.

* Ignition System Problems:

* Spark Plug Issues: Worn or fouled spark plugs can cause misfires, leading to rough running and potentially stalling.

* Ignition Coil Failure: A failing ignition coil can prevent spark delivery to one or more cylinders, causing misfires and stalling.

* Other Potential Issues:

* Air Intake Restriction: A blockage in the air intake system (e.g., dirty air filter) can disrupt air flow, leading to stalling.

* Vacuum Leak: A leak in the vacuum system can cause the engine to run poorly and stall.

Steps to Take:

1. Check Engine Light: Check if the "Check Engine" light is on. If it is, you can get the codes scanned at an auto parts store or mechanic to identify potential issues.

2. Visual Inspection: Examine the area around the catalytic converter for any signs of damage or leaks. Look for any obvious signs of fuel leaks.

3. Professional Diagnosis: The most reliable way to diagnose the problem is to take your Leganza to a trusted mechanic. They will have the tools and expertise to assess the different components and determine the root cause of the stalling and smell.

Remember: It's important to address the issue promptly to avoid further damage to your vehicle. Ignoring the problem could lead to more serious issues and costly repairs.
