A flashing check engine light means you are doing serious damage to your catalytic converter due to repeated misfires in one or more cylinders. If you get a code scanner (or go to an autozone, oreilly's etc. where they scan it for free) you will see a code such as P0301 (misfire, cylinder 1). Your catalytic converter is probably shot now. If it is and If you live in a state that does emissions inspections you will need to get the converter replaced after you fix the misfires. An old spark plug will generally cause the misfires.

To fix a Chevy 4.3 engine miss, start by checking the spark plugs and wires for wear or damage, as they are common causes of misfires. Next, inspect the fuel injectors and ensure they are functioning properly and not clogged. Additionally, examine the ignition system components, such as the distributor cap and rotor, for any signs of wear. If the issue persists, consider performing a compression test to assess the engine's overall health.
Yes, a faulty knock sensor can contribute to engine misfires. The knock sensor detects vibrations caused by engine knocking and signals the engine control unit (ECU) to adjust timing or fuel delivery accordingly. If the sensor malfunctions or provides incorrect readings, it may lead to improper timing adjustments, resulting in misfires. However, misfires can also be caused by other issues such as spark plugs, fuel delivery problems, or ignition system failures.
