While the error code won’t reveal the root cause of the problem, it should help pinpoint which cylinder is malfunctioning.If you agree, we may use your personal information from any of these Amazon services to personalize the ads we show you on other services. If a cylinder misfires, the PCM will record an error code. When something goes wrong with a modern car, the check engine light comes on. That’s why it’s best to have your buddy adjust the throttle in the meantime. The timing mark should shift as the RPMs increase. To ensure proper spark advance, have the engine revived while you run the timing light. The signs are the same, even though the distributors in modern cars manufactured between the mid-1980s and the late-1990s are computer-controlled. ![]() Because the cylinder is moving more quicker, the spark can ignite it sooner.Įngines often have a timing system that advances as the engine rpm increases to maintain correct combustion. Distributor timing in a classic car was controlled by mechanical or vacuum advances that changed with engine speed. If your engine accelerates poorly yet idles smoothly, the timing is probably not being advanced. When pre-ignition is detected, the antiknock sensor in modern engines reports this information to the engine control computer, which then modifies the timing. Using a fuel system cleaning and gas with a higher octane rating can help with knocking and adjusting the timing. Using fuel with a lower octane rating than what the engine needs or having too many residues inside the fuel system could also contribute to this problem. It sounds like someone is pounding the inside of the engine, typically when you’re speeding or under stress. The pinging or knocking noise an engine makes typically occurs when the fuel-air mixture in the piston ignites prematurely in pre-ignition or detonation. These are some problems where a timing light becomes helpful: 1. Though it can detect sparks, the timing light is so named because of its principal function of determining whether or not the ignition has been properly timed. If it fails to pick up the electronic signal, you know the problem is likely related to the ignition system. If an engine won’t turn over and you can’t figure out why you can use a timing light to determine whether or not the spark plug wire is receiving a pulse when you turn the crank. If your modern engine has a distributor, a timing light can be just as helpful as it is on older carbureted vehicles. A Timing Light May Help You Solve These Problems This is clearly displayed as a degree scale. When you press the button when the engine is on and the timing light is plugged in, the light will flash to draw attention to the current timing. ![]() This is where a timing gun comes, as you can use it to compare the markings here with those on the timing belt cover. The timing marks on the engine’s harmonic balancer or the crankshaft pulley are a helpful reference point. The timing gun detects the electric charges and releases a light pulse simultaneously as the coil pack or distributor fires thru the wire to the spark plug. The spark plug wire fire pulse can be “read” by the inductive clamp.
