[Tm135i]

Hi all,

I recently had my m135i (n55) remapped. For the first few weeks everything was fine and running great. I upgraded my charge pipe shortly after the remap as I was told they are prone to cracking. Everything still seemed fine with car, no issues. However over the last 2-3 weeks I noticed the car was slightly misfiring when idle, but was having no issue when actually driving the car. I’ve searched many forums and people suggested to change the spark plugs, so I changed them to NGK 97506s and the misfiring is still occurring when idle. I did not gap the new plugs but was wondering if it would be worth doing to see if it fixes the misfiring before starting to change more parts and spending more money.

Any help would be appreciated, thank you.
