If a vacuum leak was introduced because of your bolt in the vacuum line... possibly a "loss of power" but not a clicking sound...

Yup... their WDS can cycle the valves and will definitely help because they are activating the solenoids and actuators with it.

i have moved freel by hand the actuator of both ssv and vdi! so that should means that they are not defective right? should be the solenoid?
i also read that my obx headers has the sec air hooked up so i reinstalled the connector

okay buddy thanks for all ur help but a miracle just hapened! as i stated up! i reinstalled the air connector, moved both actuators by hand without any resistance, reset the ecu with the ''20 pump brake procedure'' went for a test drive= still the cel but no more power loss everything pulls very very hard even past 7250rpm! wow wow wow! i pulled 4-5 run 1-2-3 gears without power loss!
tomorrow i will go erase the cel at my friends place with his scanner!

So you had the air pump's wire harness disconnected and all you did was reconnect it?

Any updates on this issue, i may be having the same problem...80mph on highway and rattling noise with power loss. cleaned MAF fixed for a little while comes back intermitently. Have a K&N Typhoon intake installed (only performance part).

Please give us the history on your car. Model and miles etc. The service it's had parts replaced. Type of driving it gets(long commutes, short trip), fuel used(reg or prem), ever flooded. Just any thing that you can add. Done any decarbon cleaning?

new spark plugs and wires, coils checked and in good condition, catalytic converter checked and in good condition (not clogged). I've thought about maybe having a timing belt issue which I have not gotten checked yet. Like the other person in this post, acceleration on neutral is perfect goes all the way to 9k without any rattling noise, only makes the noise accompanied by power loss while on freeway at 75-80mph 4500rpm. Before MAF was cleaned power loss would come at 50mph or so. Something we have noticed is that exhaust fumes are not hot, just barely warm (this was a few months back when it wasn't cold yet). You could put your hand on the end of the pipe, block it and nothing, it was just warm.
