Hi, My hesitation post are probably boring you to death so I am gonna be very short.

I had the car tested at a shop and this is what they told me.

Vacum at idle is 17hg however when its droped to idle it goes down to 3hg.
When powerbraking there is 1-0hg.
They checked my ignition and eveything was flawless.
The fuel I think was good too.

They are saying clogged cat.

What do u think??

 

When I floor the car it revvs and sounds lout but it really is not going as fast as it used to.
Part throttle goes about as fast as full throttle.
Maybe that helps!?!?!

 

i wish i could help you but, after reading you other post theres not 1 idea on there that i could realy reccomend that you haven't done yet.

If you can slice the cat off for the timing being (test pipe it if needed), that can always fix that part of the equation.

The vaccum issue sounds pretty wierd....... I dunno try the cat they are pretty wierd sometimes. I think mine on my car may be clogging slightly to. I plan on test piping it here fairly soon.
