I've been all over your emails of that time to make sure I did it again correctly, accept the FP's...
Yes 100% removed the Rubber boot between Throttle body and meter. Put Glove over Throttle body and blocked rear hose ex AAR and plugged POV. Ran my little aqua pump and tested with water/detergent solution.
How's this look...


Ahhh, yeah that would probably by Glyn... he lent me the AAR to try, yeah, I'm sure he would lend them to me again... I just don't like borrowing tools like that.. I now have my kit on order so keen to use them when they arrive.

Now I have my wingman on board I will not tinker with mixtures

If I get impatient waiting for gauges I will ask our friend.

Earthquakes were 2011.

Brent,

That is the right set-up for the air leak test plus plugging the two (2) vacuum hoses that connect to the CIS rubber boot. I remember his first name as Glyn and he contacted me before I mailed his FD to NZ to send it to California. Your set-up looks good except the POV. The POV should be opening toward the front of the car and not side ways. It is better than facing rearward. You will be fine.

When you get your CIS pressure gauge, do these pressure tests:
  • Connect the CIS gauge accordingly and perform the test using the FP (engine off).
  • The first data, WUR electrical plug should be disconnected.
  • Connect the WUR plug back and take interval reading of the cold control pressures (1 min. or every 30 sec.)
  • After several minutes, the CCP would stabilize and becomes WCP.
  • There are two (2) values for WCP. Without vac and with vac applied (16” Hg).
  • You need a hand held vac pump or run the engine to get the second value.

Post the above values and we will interpret your WUR’s data. Do not forget to record the ambient temp. when the test was done. If you have any question, let me know. Thanks.

Tony
