Are you using a heated NB?

top down solutions sells a 12-20 lb spring...

NB is heated, it was running for years without the heat, but it is hooked up now. I'm going to look into seeing if one of my outputs from the WB can be wired into the ECM for a NB adapted reading and ditch the actual NB.

I'm able to achieve 20 psi with my setup, I'll check them out though, if it's external I'll block the internal one off and use it.

I pulled the codes, 32 and 42 both indicate electrical faults, open/short to ground on the EGR solenoid circuit and est circuit. they live close to each other so I know where to look. neither of those indicate why the mixture was rich on the WB. this Rich while cruising stuff started after I hooked up the power for the heat on the NB, I'm going to look at grounds VERY carefully and get the NB, WB and ECM on the same and confirmed good grounds, same for EST and EGR solenoid circuits.

You need to look up DynamicEFI.

funny you should say that I was close anyway, I just ordered it.

I just pulled the ECM and noticed I had written on it that the ECM went wacky in feb 2012 and gave three codes, one of which matched the ones I just pulled from it. So I don't think I have wiring issue, I put one of my spares in.
