SB is on the right track..
I was assuming [that never works] a code 9 on DM. BUT,
You have a HHT 009 code on the HFM module, which is , as you already know, MAF sensor problem..
Might want to check the boot clamp at the intake before anything
This would also be a flash code 4 on pin 8 [HFM mod.}
Am I with you now?
