https://youtube.com/shorts/_NIdyRbLrN8?feature=shareHi everyone. I am new member in this forum. I am very happy to have my f10 n20 520i. I love her more than my wife. I have upgrade everything, FTP charge pipe, boost pipe and turbo inlet pipe. Well! The nightmare is coming when I upgrade to MST intake. The car is idling and vibrating when I start the engine. Sometimes it will stall! The rpm jumps and downs to under 500. I tell this issue to my mechanic and he was replace the MAF sensor, coil and spark plug. The problem still. The code reader pop up 2 codes: 118002 and 102001. Any one can help me and give me a solution. Thanks!

You should check your MAF is installed correctly, ensure it's not installed backwards. Then check Crankcase hoses, make sure they are all connected properly and also not cracked. Good luck

Thanks! YTD I put the stock intake back. I check there is no crank. I will check the MAF insert correctly. Keep update!

Everything fine after put the stock intake back. And I tell the issue to MST shop. They said some of n20 have same issue. Then they are deliver the MAF spacer to me. I hope the spacer will fix that issue. I like the whoosh sound much.
