Hi!
I made a homebrew fault code reader last week..
Plugged it in (socket 14) and got 9 blinks, the analog code table shows that I got a circuit 50 failure.. But what does it mean?
Is my MAS controller broke..

Everything else seems to be ok (at socket 3 & 8).(I have a 16-pin connector).

I've started to notice a rough idle some weeks ago, my duty cycle fluctuate around 20-30% at idle.. can the MAS have something to do with it?
