code confusion

[zblackbeast]

So, the SHO when I let the clutch out idles really low like it'll stall then recover or just stall. And on the way back from the BBQ whenever wed hit a rest stop and id restart it its idle REALLY rough for a minute or two then go away. Never threw a cel or anything but I figured id run the codes anyway. I quickly last night ran a KOEO, keeping the thought of a bad MAF or IAC in the back of my mind, and got these..

552
157
519
542
115
452

Im going to rerun all the codes tonight as well as do a KOER test to see if I can pull more.. I understand the maf one and fuel pump one (iirc it trips that code if the car ever stalls) but wtf is the AIRB sensor? thanks all for any other ideas

115 - ect out of self test range - usually a bad sensor, but could be wiring issue
157 - mafs below min voltage - usually bad mafs but could be wiring
452 - no vss input - usually bad vss, or wiring is melted
519 - psps circuit open - wiring issue usually
542 - fuel pump secondary circuit failure - usually fine to ignore
552 - does not show up on my list

good luck, hope that helps
