Why does my car have an erratic timing light?
Have a look at the vids and see what you think. First video shows how a timing light can highlight erratic timing. Whatever else might be not quite right with an engine, timing marks or other features on the vibration dampener should remain stationary each time the timing light shines.
Can You time an engine without a timing light?
If you don’t get it sorted, it will affect your car negatively. Before you think of adjusting your ignition timing without a timing light, you first need to understand the type of ignition you are dealing with. Different cars have different ignition, and each of them will need a different technique to time.
How can I tell if my engine timing is erratic?
For the sake of demonstrating erratic timing I’ve aimed the timing light under the engine and by focusing on the circled area around the TDC sensor pin you can see the timing varying by up to 10 degrees I’m guessing based on the extremes of movement and relative distances between timing marks on the dampener. So what’s causing it?
How do you set timing on an engine?
So to set the timing, look out for a timing degree on the LED digital readout. Adjust the timing sensor probe to this mark. A timing light is the most common and sure method to time your engine. The light is also used to check the timing. In short, you will be able to identify any timing problems before they become serious.

Where is the timing light on a Harley Davidson?
Timing light will flash each time ignition spark occurs. Aim timing light into timing inspection hole. Front cylinder advance timing mark should be centered in timing inspection hole. If not, see ADJUSTMENT below. 6.

When does ignition timing need to be consistent?
So I’ve said in the past that no matter what is wrong with your engine that makes for an erratic idle or misfire, one’s ignition timing should be consistent during idle so far as a spark to a cylinder should be delivered at exactly the same time during each firing stroke.
