Some success ,cleaned the IACV very carefully without just dumping it into a can of cleaner and letting it soak, the piece showed plenty of internal gunk while cleaning .The fuel pressure regulator has been addressed along with a checkout of the accumilator ,cleaned injectors andchecked vac lines and secured any possible leakers for vac loss .The car fires up quicker AND RUNS GREAT ,but no secured idle .Im guessing someone in the past has messing with the lambda tower mixture set screw which I have no experience on ,Ive read plenty upon its importance of idle and its particular setup procedure but nothing more than that,time to buy some diagnostic tools.
