My passenger's side AIR hose keeps poping off under heavy throttle and was wondering if this means I have a bad valve, clogged cat, bad AIR pump, clogged manifold?

Any ideas?

Bad AIR hose/pipe check valve maybe?
Is the hose brittle or burnt inside?
That round thing before the hose is a one way valve..
Probably bad.

 

Ya, the hose was very brittle and actually crumbled in my hand the other day. I bought a new one and replaced it, but it still pops off intermittently under heavy throttle.

The one way valve, I assume it's supposed to let air flow into the manifold, and not out of it? If so, it must be bad, because when the hose pops off I have a terrible exhause leak out of that valve.

Thanks for the info, I'll replace that valve and see what happens.

That's the prob if it's burning the hose..

Yep, that was it. I picked one up from the dealer on my way home and problem solved ..... engine bay is a lot cooler now too!

Thanks for your help,

Thomas.
