I have A 2002 S2k and when I hit vtech it gets to about 7k and feels like its losing power, I've searched for answers but can't seem to find anything that fits the problem I'm having. Help is much needed so if can help it would be appreciated. Plz keep all negative and useless comments to yourself thanks.

 

are you even sure the vtec is engaging? if so how did you determine this.

 

To be honest I'm not sure it sounds like it is but i could be very wrong

 

I forgot to mention that it threw a code today for the 02 sensor, could that be a reason why its not hitting vtec

 

Check your oil level. If it's sufficient, maybe check your VTEC solenoid screen as it could be clogged. Other things you could try are resetting the ECU by pulling the backup fuse and doing a MAP whack.

 

checked the oil, reset the ecu, it was cutting out at 6k b4

 

Are you letting it warm up first? There's a cold rev limiter that won't even let you into VTEC range until it's reached a certain temperature.

 

Yea I already know about that

 

And it does the same thing in every gear not just 1st

 

are you running cats?????? i had the same problem with my old si and i put in a test pipe and it salved the problem

 

 

If your VTEC solenoid screen is clogged, you'll have the issue you're describing. I had that issue with a prelude that I swapped before. I had a clogged cat do the same thing....actually...on another prelude.

Are you sure your check engine light works? It sounds like maybe the ECU doesn't know if the car is fully warmed up.
