Vtec Problems
I recently started hearing a weird noise when my Vtec is "suppose" to engage. I disconnected my Vtec harness that connects to the solenoid and the harness to the pressure switch and the noise stopped. I got a new pressure switch and reconnected the harnesses but the noise is still there. It sounds like a rattling noise from the engine and you can hear the exhaust popping like when your plugs are going bad. A GSR without Vtec isn't much fun. Need help!

Does the vtec pulsate(engage and disengage) after the engagment point? Or basically a lack of power? Did you replace just the pressure switch or the whole solenoid. The whole solenoid has 3 bolt that hold it to the block and has a screen to trap debree. I had problems with mine and the vtec would not engage at all so i replaced the whole solenoid(which is fairly easy so don't go to the dealer) and everything works fine now.

It feels like it pulsates. I replaced just the pressure switch and i also went a ahead and replaced the Vtec gasket with the screen. One thing i forgot to mention was that the problems started right after I installed the cam seal on the Vtec side. The one that is known for leaking. I replaced it with an AZ cam seal. I don't know if that cam seal would have anything to do with it.

did a valve adjustment today but probelm is still there..the noise sounds like its coming from the bottom of the engine..could it be a clogged cat?..because after the car heats up for awhile, it doesn't make the noise...hmmm
