Either the RPM tune, which was just retuned either royally jacked something up or i blew a coil or plug.
Removing the coil plug didnt change really the way the car ran although the code i am picking up (without there being a CEL) is cylinder 4 combustion periodto short.

There is a coil and plug "performance" kit on amazon (similar/same as the other mini sites sell) i was going to get but it uses Bosch Super Plus plugs, and doesnt give any type of exact model of plug.

Anyone know if the Bosch Super Plus is equal to the NGK 1422 plug that is requested for tuned Mini's ? (colder plug)

 

Skip Amazon, because who knows what you're going to get. I would just get this kit:

oh i 100% agree with that but i need it faster than the end of next week, without paying the same price for shipping as the kit.
i got some oem coils and ngk plugs coming for saturday so we shall see, if that works, then i am so very much released, than i will invest in better coils and keep the plugs.

thats actually one of the kits i was looking at though and it uses the Bosch not NGK

 

bah i cancelled the oem coils and ordered the performance pack from ECS and manned up the overnight shipping.. cripes, 270 for a $169 parts kit that is worth far far less.

 

it was #4 coil, thank god lol.
all replaced and running again

i thought i had replaced them 3 yrs ago (5000 miles) but i dont see anything in my parts history for the mini, and doesnt mean one didnt go bad anyways.
