Loss of Power?

[Jabraltar]

Well I have no idea if anything is wrong with my car but everytime I stomp the gas it feels like I'm missing power and all I can hear is a noise that sounds like this: phhhfffffffffffffff....hopefully somebody can sound it out and understand what I mean. I've noticed that since I bought the car the power has declined a bit and was wondering if this sound was normal at all. Also the gas pedal used to be stiffer and I wouldn't have to hit it so hard...???? Thanks in advance!

I could try to make one but I'm not sure if it will pickup the noise over my intake

I also forgot to mention that when I mat it, 9/10 it smells like dirty exhaust

Okay so I found this on popularmechanics.com and I'm thinking that would be the exact problem. I'd like a second opinion though from you experienced guys.


FFFFffff ttttFFFF ffff ttttFFFFffff tttt
WHERE: Under the hood.
WHEN: Most noticeable at idle.
WHAT: An exhaust manifold gasket has failed, venting hot exhaust gases to the air.
URGENCY: It's not getting better on its own. The blowtorch of corrosive gases will eventually damage the manifold. Oh, by the way: Carbon monoxide from the leak may make you drowsy or dead.
FIX: Replace the exhaust manifold gasket before the leak eats a hole in the manifold.

Agree with the above. And just to be sure it's not something else...

Hissing while braking: brake power booster
Hissing while turning: power steering
Sucking while turning: power steering

But the strong exhaust odor pretty much gives it away. Ever swap headers and thought, "Hmm, let's rev the engine a few times just to hear and feel what it's like to have super-free-flowing-exhaust"? Yeah, it's kinda like that. You should take advantage of your current situation and rev a few Ricers at the line.

haha thanks Dr J...I'm thinking of just getting OBX headers and redoing everything from there all the way down and back to the muffler because that has a hole in it too. Never done a swap but I'm excited to see and feel the results seeing as I guess I've never felt the full power of my Solara. Woohooo!
