I have been trying to figure out why I have no power when I hit VTEC. I have no Cel or anything. Low end torque is fine, but ,idrange to top end power just dies. I have the basic bolt ons i/e/h/fpr/hi flow cat. On top of that I hear a hissing noise only when I am in gear. I went to a local muffler shop and no leaks.

anybody with info would be great.

 

are you saying that vtec is not engaging or when you git vtec you loose power.

 

Sorry, I meant to put I have no power after VTEC engages. I can still hear the crossover at 5200 rpms when VTEC hits though.

Its weird cause it feels like the car wants to go, but something is holding it back.

??

 

vacumn leak? also check your ignition components....you may have a miss.

 

How would I be able to locate a vacuum leak? I was trying to rev the car up and listen for it, but it's hard to tell.

As for the ignition components, what would I be looking for? wires? cap and rotor?

And what do you mean by a miss?

Thanks again

 

he means a missfire. check your ignition...rotor button, cap, plugs, and wires. mines had the same problem. a bad ignition coil wire.

 

sounds like you're describing some blockage in your exhaust system.

i had similar issues and had a clogged cat converter.

as usual, check your ignition and fuel system but if your veh operates normal and you have this problem only at high rpms in VTEC, check your cat.

 

have your timing checked too - can make a suprising difference if it's a degree or 2 out
