R53 First car with a weird past

Hi guys, young mini enthusiast here, I got my R53 about a month ago and I've loved every second of driving the thing, from the little things such as discovering functions on the interior that I didn't expect, all the way to beating my dad's Z3 m roadster in a hill climb race.

I've been doing mostly my own work on the car, it has been fairly modded in its past lives, with mods such as a 15% pulley, what appears to be a mishimoto radiator, and some fat brembo brakes that stop the thing as if i dropped an anchor off the back.

But I've been confronted with an issue that stumps my dad and I, when I take the thing close to redline, the gauges shut off and then turn back on as soon as I shift, now that was concerning but the car didn't stop dead in its tracks so I didn't think about it too much.

The real issue happened to me the other night, I decided to be a teenage hooligan, and I took the thing up to redline in first, shifted to second, and the whole car jerked a little bit, as if I had not rev matched a downshift properly. My gauges shut off and came back on again, and I had just backed off the throttle as of feeling this shaking. About half a mile later, the check engine light came on, I decided to stop the car and check the code with the reader I have, PO302, cylinder 2 misfire. I gingerly took the car home, and went to bed for the night.

Earlier today I re-torqued the spark plugs that I had replaced not even a week ago, and took my dad on a drive. Went into second, and revved it up, speedometer lost power as I felt the shaking started again. Immediately let off the throttle so as to not turn on the check engine light again.

Now here's the real kicker, This car has an MSD coilpack and wires, I read some threads on here, you guys hate the MSD even saying that it can harm the ECU. So I ask, would switching back to oem coil pack and wires solve this problem? And if it isn't the coils, where should I check next?

 

Thank you guys! I will be changing the coil pack back to oem, do I need to change the wires as well and rid MSD from my engine? And should I go Genuine Mini for the coil pack?

 

Update on today: it is cylinder 2 misfiring consistently, and it will only misfire in first and second gear. I did a test taking up to highway speeds in third, nothing, and I almost bounced off the limiter. The misfire also resets itself after about half a mile. New coil pack is about to be ordered,

 

I have absolutely no idea how old they are.

 

Bad news guys, coil pack swapped out, didn't fix the issue. I also swapped out the wheel speed sensor to see if that would take care of the ABS, DSC, and Tire pressure lights. I basically installed parts and made more problems. My handbrake light now randomly comes on while it most definitely not engaged, but is not related to the engine misfiring. The only victory of today was that there was a lot of corrosion on the cylinder 3 coil.

What should I look at next? I heard some mentions of crank pulley, my dad thinks it could be a fuel injector stuck open or closed, fill me in please.

 

I'll check the brake fluid, last time I checked I think it was actually overfilled. I think what caused it was swapping out the wheel speed sensor. But that isn't much of my concern as much as my engine misfiring when I put a lot of load on it. My dad suggested I ask about the relationship between the limp mode and the injectors, maybe the limp mode is engaging when I don't want it to.

 

I'll keep that all in mind, the brake pads are very meaty. I didn't actually know about the code reader thing and I guess that's why people on youtube can actually get wheel speed sensor codes. I'll add all that to my repair list and keep you guys updated, really appreciate the help.
