Intermittent problem ?

[fixkick]

89 is a very very old car.
and most , have lots of issues, including intermittent. and missing VSV , bingo.
it's not a vacuum leak, all 89s race with a leak, opposite of a stall.

well the vsv on a 89 :
1: the EGR, ok , if the EGR main dont leak, no foul
but
2: the Dash pot, now that is not a part that is optional. at all . this device not hooked up (depends on how done)
the dash pot has many roles, functions. one is fast idle at start,
and then the dash pot action it , cause an air leak as you cut the throttle preventing neck snap, and stalls.
defeating is not good.
2b: not only that , it fools the ECU, big time.
2c: Causes hard starts do to lack of air, if defeated , closed, if defeated open the idle screams like made all the time and hot worse, so the PO would unscrew the
throttle stop screw to hid the bad DP device. this too, makes hard starts.

if electric , he sees electric power drop out, that is a whole other ball of wax.
not knowing the truth here, make , diagnosis hard.

so far all we know is.:
intermittent stumble
if lamps go out and radio dies, fix THAT first. use a VOLT METER to find it.
