It was the wire that feeds the activation signal (which you call the switching signal) to the coil. The guys were able to find out that one of the 2 coil wires had a short and that was the reason the cop coil was not working. I told them I was not buying another coil because I already knew that was not the solution.

Repair: REPAIRED SHORT IN COP COIL WIRE “.I'm no professional mechanic (but i can turn a mean wrench) and wiring problems have always stumped me so I took it to my buddy at his mechanic shop. I even swapped out the injector with another just in case but it didn't improve a thing.” Also checked the fuel injector and tested for the injection signal with a noid light and they were good. “.Prior to finding your tests, I had done a compression test figuring maybe the rings were bad but the compression of #6 was almost the same as the rest. The test that finally helped was checking the switching signal with an LED that I bought at AutoZone.” I though maybe I had bought a defective part the first time anyway, I found your website and did the spark test and no spark. Both ignition coils I bought brand new (one from Autozone and the other from Orellys). Test Notes: “.I had replaced the ignitioncoil for cylinder 6 two times. I have learned my lesson, i will never wash an engine again! I did not replace any of the cop coils.

Dude, thanks for showing how to do the balance test, it saved my butt. Since i got the whole engine wet, i decided to go back to the AutoZone and get the rest of the spark plugs and cop boots. Repair: REPLACED ALL SPARK PLUGS AND BOOTS “.After pulling my hair out for a few hours, i decided to just replace the spark plugs and the two coil boots. “.On the balance test, i didn't use a vacuum gague like you ask, i didn't have one, just unplugging the injectors was enough to tell the difference.” I knew the coils were good cause they were sparking according to your test with a spark tester.” Man, i cleaned them and dried them like 3 times and also blew out the water in the plug wells and the dang missing would not go away. I took out the plugs and the cop coils and they were wet with water. Test Notes: “.What helped me nail down the problem was doing the cylinder balance test, the P0300 codes says they are all missing but it was only two of tehm. Trouble Codes: P0300 after washing engine at car wash.Ĭomplaint: “.Anytime I would drive it and give it gas, the engine would miss big time.” If you want to share your repair and/or diagnostic experience, you can use the contact form below.

In this section, is input and feedback from all of the folks who have had a similar issue with their vehicle and found a solution. You can help to improve the article with your constructive criticism or suggestions (or if the article helped, please let me know too). Well, I hope this info helped, I know it's a lot of reading (I really try to condense these articles as much as possible!) but it's all necessary. This tab usually breaks when the ignition coil is disconnected, either to replace it or the spark plugs. This locking tab is the one that makes sure the connector does not become un-plugged from the ignition coil. The ignition coil's connector's locking tab has broken.
This is also normally caused by human error after an engine replacement.
Some of these have already been covered in the article:

Over the past few years I've noticed a few other things that can cause a misfire code to set that are not caused by the ignition coil itself having gone bad. COP COIL TEST 6: Other Common Causes Of A Misfire
