TB and IAC thouroughly cleaned. No more CEL. It's running better, but still no power. Fuel trim is no longer dropping below -25%. So I'm basically down to MAP sensor right? Image attached is idle slowly up to full throttle

 

What does the map graph look like? Start at idle, and slowly lean into the gas. (in park, or neutral....)

 

Kinda like this

 

And that is slowly pressing the gas?????? That's just wrong. Either the sensor is bad, or the little rubber elbow leaks.

 

Rubber elbow was leaking. Replaced and I'm getting a much smoother change on the MAP.

So the nice part is the engine will now start and run reliably. I still have no power and still running incredibly lean.

 

I would be tempted to hook a gauge to a vacuum port on the manifold, and compare those readings to what the map is reporting.
