A pod without bracing for 5 years???
I did that in my car and my AFM f**ked up in like 2 months.
It was the dumbest mod Ive ever done to my car right after fitting and atmo BOV. Needless to say my car is back to its "stock" form and runs 100 times better.
Anyway, i think it is your AFM and it may need resoldering inside the electric circuits as when pods are not secure, they bump your AFM around and destroy the electrical contacts.
Open that fuse box and check it out. Have a soldering kit with you.
