Buick Repair Questions? Ask a Mechanic for Answers ASAP
The flashing check engine light normally means you have a cylinder misfire. This will cause the car to run rough and feel like it's going to cut off on you. If you have a parts store nearby, many will check it at no charge for you. This will usually point to the cylinder that is causing the problem so you can repair it.
This could also mean there is damage being done to the catalytic converter as well. Parking it was a good idea.
