Glad it helped. Bet you see a huge bump in HP and MPG as well for such a simple fix.

late reply, but hopefully help the next guy on mini coopers...Get a socket wrench head that will fit super tight in the ignition coil plug (With the pins, just be careful), then you will want to get a large wrench and flip it upside down and place the tip under the rubber tab and plastic that is supported by the socket wrench head. Just pry it up with the roundness of the large wrench upwards and then you will eventually be able to pop it out. The only way I was able to do it without damaging them, or breaking the plastics.

You need to troubleshoot cylinder 1. Spark test, injector test, compression test. It has to be missing one. But this isn't something I can give you step by steps on, although I have compression test videos and there are videos on each of these all over KZfaq. Get results and I can provide some guidance.

@@paulkelley86 I really appreciate your response. Been dealing with this all day today and your video helped a lot

You could pull the coil and lay it on the valve cover with it connected to see if it sparks. If it doesn't spark yes it could be the wiring from the ECU. If it does spark, the misfire could be caused by a problem with that cylinder injector or with loss of compression in that cylinder.

Same here. 😂

same here😢

Unplugging is just as good, but will set additional codes which is also no problem, just clear them.

Right, you are seeing if the code moves following the coils. You need a scanner to check dtc

High Pressure fuel pump.

@@salt106035 sold it to carmax for 4K lol didn’t bother taking the risk, was a fun car though

@@salt106035 I replaced the hpfp and still have the issue though it helped for a day. Now when I do this ignition coil trick it stalls on all four coils. Does that mean they’re fine I’m assuming?

You did not get shocked that day with the coil amd spark plug simulator demo in the classroom? Not that bad. Kinda like a bee sting but no after pain

Paul Kelley nope don’t recall. definitely gonna try this next time. i usually switch the ignition coils and rescan but i end up with a stored code and a new one so it can get confusing sometimes.

@@ivannava1352 I get ya. This way is only good when it is misfiring at that moment. Or sometimes if you get a coil circuit code. If the misfire is intermittent not so helpful

It is very unpleasant. Hight voltage 10x worse than household current. 😖

More than likely will damage get catalytic converter due to raw fuel being pumped into the exhaust. Some cars shut the injector off but not sure about this one

You can disconnect it true, but it will likely set codes for primary coil circuit open. And if you are going to swap, you will need it to be unbolted and the connector removed so either way. Personally I find it easier to pull the coil and l can also hear the secondary spark occurring down in the tube if the could is in fact firing. Personal preference.

Because it is misfiring. Which isn't necessarily caused by coils, or even lack of spark. It could be a fuel or compression problem. Commonly people try to save money by swapping parts, then when it doesn't fix it, they drop it off at a shop to be diagnosed, some of those people are upset about a diagnosis charge, but they don't seem to mind blowing money on unneeded parts. Your vehicle really needs to be properly diagnosed, and that is going to take time by an highy knowledgeable technician... who is probably going to want to be paid for his/her time. The coil swap cylinder to cylinder is easy DIY, outside of that I don't recommend it being DIY.

Thoughts on when it stalls on all four coils even after replacing with a new hpfp?
