Hi Everyone:
So i knew there was a problem with number 2 cylinder since there were so many misfires in the history for that cylinder.
When number 1 and number 2 coil current ramp both tested the same i knew the coil was good.
That's when i removed the spark plug and found the arcing from the spark getting past the coil boot.
For more information be sure to visist: www.johnsadlersautorepair.com

I just swapped a new motor in my h3 but the old engine it through the rod on cylinder 1 . So I get it all back together and now cylinder 1 is misfiring and I’ve changed plugs and coil multiple times I’m lost at this point next step is a compression test I guess but it’s just weird cylinder one went out on last motor and the misfire could of been the culprit?

Good afternoon, did you use the same fuel injectors?
@JohnSadlersAutoRepair

If they fuel injector is sticking open will cause misfire and fill the cylinder full of raw fuel. You can put an ohm meter across each one and see if one is open ( no reading on your meter). They should all be close to the same reading.

Hi Lisa, what's the year , make and model? Check with your local auto parts store, many of them will read the code for you from the Check engine light. Send me that info and I'll help you.

Don't drive very far with the light flashing, it will damage the catalytic converter. You will most likely have a misfire code.

Your check engine light is blinking, that means bad misfire. get a scan tool on it and it should identify which cylinder is the problem. then check the coil , you can swap with the cylinder next to the problem one and see if he code moves there. If it does you have a bad coil, look closely at the coil boots also, you can buy them seperately.
