Loud/Weak Vtec (I've searched)

I've got a 2000 Prelude, 230,000 kms, 5 speed.
A few weeks ago while driving my car, I pulled out to pass a car on the highway, "hitting" vtec, I noticed the car didn't pull nearly like it should and was very loud as well.

Yes, I have adequate oil in my engine, and it is at operating temperature when this occurs.

Things I've checked/replaced:
-Checked timing, seemed to be in time
-Checked cat. converter
-Changed air filter
-Changed spark plugs
-Changed fuel filter
-Changed distributor
-Changed oil and filter

If anyone has any other ideas for me to try, please let me know.

Have you even tried checking the vtec solenoid? You probably didn't even search. lol
If it's weak, the screen on the gasket might be gunked up.

Re: Loud/Weak Vtec (I've searched)

I have known of quite a few of these kinds of problems happening. Like previously said you should check the vtec solenoid. I would also check to see if your valves are adjusted properly.

Re: Loud/Weak Vtec (I've searched)

I cleaned the screen a little over two months ago. I thought that if the solenoid wasn't working properly, vtec would not engage at all.

I will do a valve adjustment and get back to yahs.

Re: Loud/Weak Vtec (I've searched)

well if the valve adjustment fails(if it's even out of spec) maybe you should look into a more mechanical issue in the head.

Re: Loud/Weak Vtec (I've searched)

SHdriver once told me that some preludes lose vtec after a while. I think you need to take it to Honda and RE-Vtec-a-lize it. Just my .02

are his posts still around? some of the garbage he said was so bad it was funny.

tho ive always wondered was he genuinely retarded? or just trolling?

also check oil pressure if oil pressure is not what it should be that would effect it.

same with operating temperature IE: cold vehicle

Re: Loud/Weak Vtec (I've searched)

I know it's been a while since my last reply but, the valves were withing spec. I'm starting to lose hope in my engine. Although, yesterday I was driving and my CEL came on, it was for the EGR. Could this be the source of my problem?

wouldnt hurt to clean it. I cleaned out my severely clogged EGR and my IACV and noticed a major difference. mostly with idle but with power to some extent as well.

just out of curiousity, did you check your ignition coil and test it? mine was causing a lot of issues for power and only randomly threw a code.

Re: Loud/Weak Vtec (I've searched)

I cleaned the EGR valve. Did not solve my problem, however it does seem to run a bit smoother. I will try to replace the coil tomorrow. Thanks for the advice!
