Is there a fix for coil on plug ignition?
In case you’re not familiar with this (infamous) issue, the fix is to replace all the ignition coils and the PCM, which requires reprogramming the PCM, which in turn requires two original ignition keys to reprogram/reboot the anti-theft system.
What causes no change in primary current on coil?
The monitor will see no change in primary current if the winding inside the coil is open or shorted. However, a broken power or ground wire or a failed coil driver can all cause the same symptom and the same trouble code.
What causes a misfire on a coil on plug?
When the engine cools off overnight, the fuel in the rail cools and condenses, leaving a small pocket of vapor at the highest point in the rail, right next to injector No. 1. Naturally the misfire clears up quickly as the rail fills with fuel, and there’s no reason to chase this problem any further (how could you possibly fix it?).
Can a DVOM test a coil on plug ignition?
By now you get the point that a scan tool and a digital volt ohm meter (DVOM) don’t always provide enough information for an accurate misfire diagnosis. Any ignition system can be affected by heat and engine load, so testing a coil with the engine running gives you a more complete picture.
What happens when the seal on the oil pan plug breaks?
If the seal breaks or the bolt threads are destroyed, oil will leak. Engine oil is necessary to keep moving car parts lubricated. When oil leaks, a lot of friction is created, which later destroys various engine parts. 1. New hole 2. Helicoil repair
Can a spark plug be removed with anti seize threads?
When the DIYer or professional tech went to remove the spark plugs, they would often rip the threads right out of the cylinder head. That’s when spark plug manufacturers and carmakers started recommending the application of a small dab of anti-seize on spark plug threads. That way, the spark plug could be removed easily the next time.
