Ok, Heres the MS2/specs
JB Perf P/H board + cam sync -running sequential pushin PTE low Z 1000cc Injectors

Issue: out of no where, i was driving on a known good tune, and i get this insanely lean condition. Its lean @ Idle, as well as driving as I was limping home. Typically I idle @ 14.4 , now after this intermittent issue, I idle at 18+. I can see the PW do some funky things so my initial conclusion was a fuel issue. Pump is checked, as well as filter (brand new). Now this issue is intermittent, Took it out one day , ran like a top. Parked to get a drink, restart the car, and instantly feels like its running on 2 cylinders. Now today, I start it, and seems to do fine, Except i notce my ego correction has pulled 15% of my fuel to keep a 14.X afr, which is unusual (typically im +/- 1%) . But it continues to idle. I goose it, and still runs ok. Then, i touch the top of the MS, where my P/H board is mounted via plastic screws, and instantly, the issue is present.

That said, how can i probe/test my P/h board for loose connections? Or is this a weird coinsidance?
Ive attached a MLV showing it idling fine, then on the 2nd log, showing the issue. Ive also attached my tune.

Motor is a built 2.4 EZD running crower 3 cams, yada yada. The plugs also reveal one cylinder seems a little leaner than the others.

Any help/Advice? I dont mind sending my MS to be looked at.. but my experiance with Symtech labs is rather poor and i need it to be a quick turn around, so if anyone has suggestion about where i can send it, that would help too..

Also, IIFC, pin 40 on the MS2 daughter board is broken , but making connection. It looks like pin 40 is a +5v connection, could this be the issue as well? Im not sure what that +5v actually runs.:
