If the VTEC yo wasn't working the CEL would be on

 

I appreciate everyone's input. It really is great to have a group of people that love the S2000 as much as I do, and that are always willing to help fellow "aficionados/enthusiasts"

Thank you all.

I posted a thread a few days ago about my VTEC not engaging. I appreciate everyone's input.

Based on the input I received, I realized that my VTEC is in fact engaging. The car runs well, I can go to the red line with no problems.

What I have recently noticed with my car, which by the way is stock, is that now I cannot feel the VTEC kick in like I used to. I could actually feel a pull at 6,000 RPM, but now that is gone.

As far as the engine sound, it gets louder past 6,000 RPMs, but I cannot hear that roar that people talk about.

What could be causing this? The oil level is fine, the Engine light does not come on, there are no codes, and I have not done anything to the engine.

Thank you very much.

Dirty air filter is a BIG cause, can make VTEC feel almost non-existent.

 

I haven't checked the filter, but I will thank you.

 

What about a bad clutch? Maybe slipping, so when the "TEC" hits, shes slipping just enough that you dont feel it like you used to. Possible??????

I don't know Chad. I have also experienced some issues with rough shifting. I always thought that the S2000 prided itself in having a very smooth gear box, but after my own experiences, and some of the feedback I received, I pretty much surrendered to the idea that the S2000 has some issues with shifting, especially with a cold transmission.

Maybe my tranny and VTEC issues have the clutch as a common denominator. My car is still under warranty, but my impression is that the mechanics at the local dealer are not very familiar with the S2000.

Try driving fairly slow in a high gear..... lets say 5th or 4th gear, at about 2-3k rpm. Mat it, and see if the revs seem to gain at a similar rate as the speed. With a heavy gear, under load is where you typically can see slip in the clutch. This may not be as effective due to the lack of torque in the S2000 down low. I assume you have no intake? Did the car used to be different as far as VTEC engagement is concerned? What kind of mileage is on the car, are you the only owner? Mine is an '05 with 27,000km. When the car is cold, it will be VERY notchy in EVERY gear until I have driven about 2-3kms or so. It really sounds like a clutch issue to be honest. Unfortunately, if this is the case, Honda Warranty will not cover it, due to being a wearable item.

buy an aftermarket intake.
