! Pressure test even NEW solenoids !
Since I was having weird boost patterns, esp. after high-RPMs, I used Dave Disney's write-up to check my charge control and turbo control solenoids in the dreaded rat's nest:
http://rx7.voodoobox.net/howto/solen...oid_check.html
BOTH we're not responding well (quick bleed-off) to 12-15 psi.
As Dave said, even his NEW ones did NOT pass his pressure test.
I ordered all new solenoids, and ONLY TWO of them passed out of eight (8) NEW solenoids from Mazda.
Of the six (6) that did not pass, two (2) were questionable and four (4) just stayed closed for 3-5 seconds after releasing 12VDC.
In short, PRESSURE test ALL SOLENOIDS.
:-( neil
BTW: when will Saxyman990 get his external solenoid kits out:

FWIW: I was able to replace both the charge control and turbo control solenoids WITHOUT removing the rat's nest, using some long and curved hemostats.

It seems that the oem solenoids are not designed to work after 12-14 psi (but the black box solenoids work even to 17 psi).
My replacement kit is almost ready...
