The ECU holds the VSV open when the throttle is raised off idle, the last years of these 2 generations of G16b , the last one needed rear wheels to turn (mph > 0 in dash)to open the VSV
i bet yours does not need rear tires off ground. as seen in 1996up.
at no time do they stutter, the VSV is either open or closed, not stuttering.. ever. or its bad. news.
The ECu goes nuts for 2 reasons
bad CAP #1
bad power, grounds mostly here.
head lights dont dim when vsv goes nuts (turn them on)
battery voltage over 14vdc when vsv goes nuts? (bad alternators can blow out 1 or 2 phase of diodes inside or even short them and make HUGE 12vdc power noise (giant) even will find C1 in the ECU is weak (not spec) and so is 2 problems. one helps the other fail.
i use scope to see noise many shops have none.
ever even looked at the ECU lid off yet.?
C1 leaking acid, or sides split, or bulging or blew its lid, looking is a magical thing on things that look bad. but sure looks alone are not proof of good. if looks ok only meter proves that.
if you had the real FSM book , it shows every inch of the harnesses. ever ground every inch, and if you had that, youd see all those harness pig tails for ground if that harness is even stock.
the case of the ECU uses a different ground,
that enables all inputs filters. in the ECU. so the ECU has many grounds, all must be good.
what is your ecu part number dash 58Bxx or 77Exx what is your xx? http://www.fixkick.com/ECU/ECU16v_92-95.html
here is the corner cap c103 is real number, in the corner below is old sammi leaking like mad.
