Cel P1259
I just went to Autozone and the code they pulled was P1259
Which is the reason why I can't rev past 4K RPM's
The problems could be one the three
1) Low Oil Pressure
2) Blocked oil Passage
3)Failed VCT oil control valve
I checked the oil and the level is perfectly fine.
And other suggestions before I go to the dealer to get raped

w/ ur vtec off, u should still be able to rev higher then 4k, but it will be powerless, actually u can go up to 5.5k and if u stay there for a long time, u'll probably blow something up in ur motor.
how dirty is ur oil?
i'm not sure exactly what the problem is, but u can probably clean out ur vtec solenoid and see if it helps.
take out the three bolts, take off the solenoid and spray some carb cleaner in there, u'll see a little piston stickin out (the solenoid goes above it), push it down several times to check the movement of it to see if its clogged. if it moves up and down fine, then its good. also grab a vtec solenoid gasket from ur honda dealer (its like 3 bucks) change out the gasket and put it back together. hopefully that should help.
If that doesnt make a difference, u gotta do the vtec solenoid diagnostic.
u'll need some one's help w/ this.
get in the driver's seat and turn ur car on, rev it up to check to see if it revs up normally or slows down after 3k rpm.
if it slows down, then tell ur helper to hop in the seat and rev it up to 2.5k rpm,
disconnet the vtec solenoid and hot wire it, run a direct connection from the battery to the solenoid, and tell ur helper to rev it up and see if it goes up normally (which it should) if it does then u've got an electircal problem some where. if it doesnt, then ur solenoid is bad.
do this and tell me what happens

OK, I took off the VTEc Solenoid and here's the results.
The oil looks pretty dark so I'll change the oil.
However, the little piston thin that goes into the solenoid, I pushed it in and it hesitated to come back out. So after pushing it in a couple of times it goes in and comes out fine.
Should I go ahead and spray some carb cleaner in there or just put a little clean oil in there.
Also, I didn't see a "screen" that people were talking about when I took off the solenoid.
Here's a couple of pics.

that black gasket around the vtec solenoid is the gasket u need to change out.
Also get a magnet and pull the piston out, there's a spring underneath it, (BE VERY CARE FULL W/ IT CAUSE U CAN LOOSE IT EASILY)
check the spring to see if it looks/acts normal and yeah, spary some carb cleaner in there and if u can stick a tooth pick to clean sludge thats probably stickin inside too (also w/ the solenoid)
The screen/filter, goes b/w the head and the piece that the vtec pressure switch goes in. i dont see the pressure switch in teh pics, will have to check another f23 accord to find it. if u know what i'm talkin about, just pull taht out and clean it w/ a carb cleaner.

i also saw taht ur solenoid's shell is pushed in a little from the top.
i'm gonna have to check mine and see if thats how it looks.
heres a diagram of f22 vtec. the filter is shown there.

Well.
I pressed the piston thingy in back and forth and there is no longer any resistance.
I sprayed a little carb cleaner there and I also put a little oil there also.
After that I reassembled everything, erased the code, (said a little prayer) and started the car.
CEL stayed off and car goes all the way to 6800 RPM's now.
Actually, it seems like the car pulls a little harder now.
Maybe because I went back to winter mode, (I took off the 18's and put back on the stock 15's)
Tomorrow I'm definitely gonna clean it out much better as you described.
Thanks
