Woo hoo... Thanks guys. Seems to be fixed...

I looked at the intake mesh in the wur. Honestly, it looked awefully clean. I used some air at 40 psi to blow onto it. Must have done something, as the cold control pressure went down to 35...

Then, blew out the tiny outlet-line from the wur to the fuel distributor. That knocked the cold psi down to 22-25 or so.

Warm pressure of 45 or so, at 45-50 degrees.

Started the car, ran absolutely like crap. Super rich idle of 10 or so. Adjusted the afr ratio at idle to 12.5 or so. Ran well again.

With the o2 sensor disconnected getting a cruise afr of 13.5 to 14 or so.

Stepping on it, with the turbo starting to kick in, drops to 12 or so. Couldn't go further as its snowing out side...


The 02 sensors circuit works again also. Yey!!! It does seem to vacillate more, though. Previously it kept the afr between 14 and 15... Pretty steady.

Thanks guys... Blow out that mesh in the wur, even if it looks clean... Seems to do something.

Thank you, Bo
