Why is my 2001 Cadillac Sevill sls stuttering and running rough after oil change how do you reset check engine light?

I understand you're having trouble with your Cadillac after an oil change. It's important to address this issue carefully, as it could be a simple fix or something more serious.

Here's why your car might be stuttering and running rough after an oil change:

* Loose or Incorrectly Connected Oil Cap: A loose or improperly seated oil cap can create a vacuum in the crankcase, affecting engine performance.

* Incorrect Oil Type: Using the wrong type of oil can cause engine problems. Check your owner's manual for the correct oil viscosity and type.

* Oil Filter Issues: A faulty or incorrectly installed oil filter can restrict oil flow, leading to poor engine performance.

* Air Intake Issues: During the oil change, something might have been accidentally disconnected or disturbed in the air intake system, like a hose or sensor.

* Spark Plugs/Wires: While less likely, the oil change might have jostled something related to your spark plugs or wires, causing misfires.

How to Reset the Check Engine Light:

Important Note: Resetting the check engine light doesn't fix the problem. It only clears the code stored in the car's computer. You need to address the underlying issue.

Here's how to reset the check engine light:

1. Disconnect the Battery: Locate the negative battery terminal and use a wrench to loosen and disconnect it.

2. Wait: Let the car sit for at least 10 minutes with the battery disconnected. This allows the computer to reset.

3. Reconnect Battery: Reconnect the negative battery terminal.

4. Start the Car: Start your engine and allow it to run for a few minutes.

5. Check the Light: The check engine light should be off, but if it comes back on, you need to have the car diagnosed.

What to Do Next:

1. Double-Check the Oil Cap: Make sure it's securely in place and tightly fastened.

2. Inspect the Oil Filter: Check that it's correctly installed and there are no leaks.

3. Check the Air Intake System: Ensure all hoses and connections are properly secured.

4. Check the Spark Plugs and Wires: If you have experience, inspect these components for damage or looseness.

5. Use a Code Scanner: If the check engine light returns, consider using a code scanner to get more information about the issue. This will give you a better idea of what needs to be addressed.

Professional Help:

If you're unsure about any of these steps, or if the problem persists, it's best to take your car to a qualified mechanic for a thorough diagnosis and repair.
