Would it make a difference in power if my engine was revving as opposed to in gear with a blocked cat?

I think my car is blocked as it was cause back pressure through the gasket, but the engine revs higher than is does when in gear.

Is this still a cat problem or more of a tranny problem?

 

bump?

 

By blocked do you mean clogged? And revving in gear meaning while the clutch is engaged? Specify a bit more please...

Your car should rev just like in neutral if your clutch is engaged.

 

let's break this down.

While driving with a presumed blocked/clogged cat....my car had no power and would not rev at all.

When the daylight came out i noticed there was a surge of air coming from the cat's gasket, but could still rev higher.

is this still a cat problem or a tranny problem? (both have been slowly going on me)

 

Replace the cat first. Since its in neutral it doesnt have to spin the tranny/wheels so it takes much less effort to get the motor going.

 

that's what i was hoping for

the new test pipe is coming soon so i'll replace it and see then

thanks
