Help with vtec

Ok so I have a 97 Prelude h22a4, It has about 200000 miles on it and I've had it for almost a year now. It has always ran great never gave me any troubles. Lately I have noticed it seems like vtec isnt working sometimes. Some days i'll drive it and when I get on it Vtec kicks hard then other times it seems like it never even hits vtec and my vtec kicks in at about 4800. I can run it to 6k or so and vtec will never kick in. Is that a vtec solenoid going bad or something esle?
Thanks for the help in advance!

Re: Help with vtec

Start out by checking to see if your VTEC solenoid is clear of any oil gunk. The solenoid is located on the left side of the motor beside the dizzy. There's 3 10mm bolts holding onto the motor. Place a rag underneath bc a small amount of oil will drip once it's loosened. Once removed you shall see a screen filter within a rubber gasket. Take a knife or short flat object to pry the filter gasket off of the solenoid and clean any gunk off with a bottle of throttle cleaner.

Also check the wiring connecting to the solenoid to see if the wiring might be worn or it might have been tugged off.

Re: Help with vtec

yea wat they said and make sure ur car is warmed up and has enough oil pressure to pop vtec. ive tried it for the hell of it by trying to go into vtec while the car was still kinda cold and it sounds horrible when i pass 5200 rpms lol. Once the car has enough oil pressure ur good to go. i got a buck fifty one on the odo.

Re: Help with vtec

Sounds like a dirty/clogged solenoid to me.

I wouldn't be pushing 5000 RPM's with a cold engine...especially one with over 100 k miles.

I have checked the oil level, It is dead on the full mark and it's only been 1000 miles since the last oil change. I have not cleaned the solenoid yet but I will clean it tomorrow at work and see if it helps. Thanks for the info.
