What happens if there is no cylinder misfire counter?
What happens if there is no cylinder misfire counter?
If there is not a Cylinder Misfire Counter, then you might have to switch components—such as coils, spark plugs, etc.—in order to isolate the root cause of the misfire. It is also important to note and record any other codes because the engine may be misfiring due to the failure or malfunction of another system or component.
How can I tell if my car has a p0301 misfire?
Pay close attention to the engine load, throttle position, RPM, and road speed because a P0301 (which is a specific misfire) can sometimes be difficult to detect. If the Engine System has a Misfire Counter for specific cylinders on the Scan Tool Data Stream, pay very close attention to the cylinders (s) named in the misfire code (s).
Why does my car misfire all the time?
An Ignition System problem is one of the most common reasons for an engine to misfire. As the spark plugs, ignition cables, distributor cap and rotor, and ignition coil wear over time, their ability to transfer the needed spark to ignite the air/fuel mixture inside the combustion chambers becomes compromised.

What causes a car to set a misfire code?
Vehicles can set misfire codes when badly warped and out of round rear brake drums violently jerk the entire powertrain when the vehicle slows from highway speeds. Make sure that you have the vehicle properly inspected in order to determine the root cause of the misfire.
What causes a Chevy Silverado 1500 to misfire?
Fadi answered 3 years ago p0300 indicate random cylinder misfire, usually the cause is 2 or more cylinders misfiring, if you know someone with a higher end scanner that does live data you can actually see which cylinders are misfiring in real time (makes things a lot easier). 36 people found this helpful.
What causes engine revs to drop when idle?
3) Once at normal operating temperature, the engine misses badly while idling. It idles smoothly for a second or two, then misses, which causes the revs to drop suddenly, and then the control system seems to increase the idle speed to counteract the drop in revs for a second, and then the cyle repeats.
Can a bad timing chain cause an engine to misfire?
Engine misfires. The timing chain method is more common with consumer vehicles and high performance engines. Over a period of time, the timing chain can stretch, which can cause the chain to skip a gear on the cam or crank shaft. This results in the engine’s timing to fall out of calibration and often results in a misfire.
How can I tell if my timing chain has slipped?
Listen for any abnormal engine noises, with the engine idling, in the vicinity of the timing chain cover. Chains that have slipped time have slackened and can sometimes rattle during cold start or idle, or produce a swishing or scraping noise.
Why does my timing chain rattle when I idle?
Chains that have slipped time have slackened and can sometimes rattle during cold start or idle, or produce a swishing or scraping noise. Loose chains typically hit the inside of the timing chain cover.
