Sounds like a rod bearing. Time for a rebuild job.
if its a loud knock from the bottom end, DO NOT run the engine, it is likely a spun bearing; have a professional look at it
That is the knock sensor
You have another problem other then the knock sensor if the engine will not start and run. A knock sensor will not cause the engine not to run.
No, it will not cause the engine to knock.
The knock sensor, in your 1997 Chevrolet Lumina, can be found on the front of the engine. The knock sensor is near the top of the engine.
Gm used a short piston skirt on this year. The knock is piston slap that normally goes away when engine warms up. Sounds bad, but should not cause any problems.
The 2006 Dodge charger knock sensor is located on the back of the engine. The knock sensor will be near the bottom of the engine cover.
Need to know what engine it has.
engine misfire. i have a '96 Chevy blazer but i don't have that problem, i was reading reviews on the car and found out that some of them do that.
Severe spark knock (pinging) can damage the engine. Knock sensors detect spark knock (pinging) in the engine. They send that info to the ECM (Engine Control Module). The ECM makes temporary adjustments in engine timing to eliminate the spark knock.
The 1997 Chevy 1500 pickup truck 5.7 liter engine knock sensor can be found on the front of the engine. You will need to remove the front engine cover in order to access the sensor.
It is over by the starter, and screewed into the engine block.
