was kinda honping to try the vacuum first before spending a ton of Money again on This ****ty car and taking it all apart.?? the high revs is me putting My foot down ?

check all hoses around intake manifold for holes cracks

I would clean the throttle body and check the brake servo vac hose for security at both ends.
If the throttle body itself is loose or the inlet manifold you can make the revs change by pushing or pulling on them.
