I'm going to go through the fuel system tests methodically. I tried to just jump and it obviously didn't work. I have no idea whether the CO levels are correct. The car ran decently when warmed with the old ICV installed but not perfectly and surged when cold. Now, its the opposite - good when cold, surge at warm idle.
My new ICV is from maf-shop above.
I note that Greasy Fingers had similar results with the ICV.

The good indys are booked months out and I like having equipment to do most of my stuff.
Is there an easy DIY exhaust analyzer to set CO2 & HC? My searches have all lead to commercial analyzers that are over budget given how often I'll use it.
