Diagnosing ICP pressure.
It seems to come & go. I get P1280 frequently and it seems to 'short out' or something intermittently where I'll get surges of massive power with black smoke, extremely lopey idle, and stalling. I've repeatedly tried wiggling the wiring with the sensor connected and the engine on and it seems to do nothing. If it runs decently with the sensor disconnected and only craps out when it's connected is it fairly safe to say that the sensor is indeed faulty?

Fleabay ICPs are cheap, and included with that cheap price you get a long and storied Reputation for continued Grief and Despair. Gotta go OEM here.

I saw super cheap ones on Amazon but I know this is one of those "OE only" parts. I considered a cheapo just to test, then realized that no matter what it does it won't be definitive since I don't know what that $20 sensor will be doing. I just don't wanna blow $140ish on a part I don't need. It was oily, I cleaned it out, no oil has reappeared but I've only got a couple hours on it since cleaning. This is a new purchase and I'm diagnosing/fixing lots of stuff as I go though it.
