NGK BKR5E stock heat range BKR6E 1 step colder and BKR7E 2 steps colder.

I would do a BKR6E gaped at 28.

Ok, I can pick up some BKR6E's. Like these?

And you'd gap them at 0.028"? That's smaller than I expected, but what do I know anyways...

any of the spark plug wells have a good amount of oil in them?

Do they not have an auto parts store up in Wisconsin?

They do but since I live in the dorms while I'm at college, I'd rather save some money and come home on the weekend to new parts, then I actually have time to install them too

So, I took a look at things again today, I apologize in advance for this long rant.

First of all, I had the battery disconnected for the past 4 days. I decided to come back and take a look, so I hooked the battery back up and then started the car. Stupid me forgot that this would erase the CEL. And now it won't come back on!

Anyway, I proceed to pop the hood and was going to test the spark plug wires. To do this I planned on pulling each one off the coilpack and find which wire could be pulled and not make a difference in the way the car ran. I started with the first one. As I pulled it off the coilpack it still was sparking but once completely off, the car still ran the same (misfiring). This made me think it was the first cylinder. Then I pushed it back on (sparking again, close to the contact), and proceeded onto the second wire. As soon as I pulled it, it sparked and the car shut down real fast. Now I was sure it was the first cylinder.

I was going to do the same test again, but this time try pulling off the wire from the spark plug end. I did this (and it sparked again), but once pulled, still ran the same (misfiring). So if the wire is sparking on both ends when removed, doesn't this mean the wire is still good? And if the wires were good, I planned on pulling all the spark plugs. I did that and all the plugs were pretty black from the car running rich (it's turbo, and was tuned this way), but other than that they looked good.

Either way, I wanted to replace the first spark plug because that was the cylinder giving me trouble. So I ran to the auto parts store and bought one of the same plugs, gaped it correctly and threw it in. Fired her up and still no change.

Now I was told that I could clean off the Crankshaft Angle Sensor and it might help the situation. So I did that, pictured below:


Fired her up again, still misfiring. Is this sensor placed too far away? I heard it's only supposed to be a credit card's thickness away. Where else should I clean off... this is really starting to aggravate me.

Here is a video of me pulling the 1st plug from the spark plug, you can hear it sparking and then not make a change in the way the car is running.


And here is a video of the car running (still misfiring), and me revving it. Don't mind the bogging down it did at the end of the video, that's from my BOV not being recirculated.


The videos are cell phone quality, so I apologize for that. It's not very easy to hear that the engine is misfiring, but it's definitely not running right. I don't know where to go from here...

Miata is working now, just running a bit more lean in boost than before. But it was running way rich before. I'm glad it's up and running again but I'm thinking of selling it. School is first priority and I need the money for it. I would love to pick up on later down the line when it's more practical after college.
