Bad Spark plugs? usual idle, and rough acceleration

I drive 08 335xi and has about 90000km or 55000 miles on it.
Only mod I have is DCI and Jb4 and I was doing 1st gear WOT and into 2nd i heard big pop noise and check engine light came on. I pulled over and cut the engine and started up the car again and check engine light is still on and i noticed it idles very unusual and very roughly. Also it drives very rough from slow speeds. I think my sparkplugs went out and starting to misfire? since i did not change the plugs since new. What do you guys think the problem is?

You may have blown out a spark plug. Old plugs and coil pack break quickly once your tuned. Buy the spark plug tool on ebay and change them yourself.

Since you have the JB4 why not read the codes This will tell you exactly whats wrong. If you hear a pop your charge pipe might have failed or the FMIC to CP pipe popped off.

If the plugs haven't been changed in the last 20-25km then I would definitely get that done.

Spark plugs needs to be changed every 25,000 miles for tuned vehicles.

I'd start there if you are getting misfires.

I've noticed my plugs aren't much good after 12k - 13k miles if they're run hard. I had planned on a 16k mile change interval but get misfires under full load every time as I approach that mark. New plugs and it's as good as new every time.
