My 2009 mini is going this but only under full throttle and high rpm turn headphones up.

 

Find out what code it's throwing and maybe we can help.

 

The Codes are for O2 ( catless downpipe ) and then on a Walmart $20 scanner P0320 most of the time the check engine light for limp mode goes away right away or sometimes just flashes.

 

????? Sorry.

 

So Today I was able to clear all the codes do a pull and let it cut out again and give me the limp mode. I scanned the car and it came up with no codes. so I decided to do another pull with in limp mode and it still was cutting out just like the video. I recently replaced spark plugs with NGK 1422 and spaced to .022 and new ignition coils and a new intake hose. My car is all stock expect for a catless down pipe. I do know I have a small exhaust leak where the down pipe and jcw exhaust meet but I have always had that and nobody can seem to fix that. I thought it might be my high pressure fuel pump so I don't think so.

 

NGK1422's should be gapped at 0.024" (6mm). Note that these are one range colder than OEM and typically need a few more mods than just catless downpipe. You might want to talk with a tuner to get rid of your limp mode issues --- catless DP's are pretty common for them. Are your new coils OEM or aftermarket?

 

Okay I will take a closer look at the gap and they are Delphi ( https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 ) I will order stock plugs and see if that changes anything.

 

I read somewhere that OEM coils are designed for iridium plugs. Are you sure this is an OEM replacement coil, for your model / year? Amazon description doesn't mention Mini. If still available, maybe try your original coils?

 

My car did the same thing on stock coils that's why I replaced them as it was time for new spark plugs anyway. I just thought it was bad plugs, bad coils that made the problem.
