Peter,

Worked on things a little more last night, the vac transducer to the charge control is bad, as are the other 2, I can pump it down but it won’t hold very long, I will replace this. The vac line to the charge control valve (wastegate) was leaking, replaced that. Now shifting is much better no but still a little abrupt but no chirping the tires from 1st to 2nd , the A/C always worked great, go figure, except for the auto fan, but now that was working this AM for the first time!

Checked the overboost valve, lines are clear, I can blow thru both connections on the valve they both seem to vent out the cap on top, is this right?

Also rechecked the ALDA directly, I can pull a vacuum on it but I leaks down, about 30 sec 15”hg to 0, good? Bad? OK?

Thanks for all the info!!

Eric
