like it says what would cause this and i am not talking like a lil rev it revs fromm like 700 to almost 1700 rpm? juss sitting still pumping the brakes

 

the vacuum your brake booster uses comes from where?


THE MOTOR. Or more specificaly, the intake manifold. check all your vacuum lines, and your brake booster.

 

Check there is a Oneway Valve,

 

check your brake booster hose, drivers side on the firewall. Its a fat hose that connects into another fat hose its a fat bitch hoe.

 

ur break booster is weak,

 

jakscivic pic i think, if you want it down I'll do it per request. All the way to the right above the master cylinder.

 

That's a nice setup. Lota room for cleaning it up...but I like the idea.
That way you can weld the manifold up and make it look purrty.

 

I've always been able to do that in all my car. Even my dad old 2002 civic I was able to do that, even my moms 2005 Kia. Sure, the newer it was, it never went that high, but I could get my dads old civic to 1200rpm by doing that, always thought it was normal?

 

mine does the same, i dont thinks it goes that high but i never tried?
