Hello,i am sory for my english

I am from Slovenia and i drive Honda s2000. last year in summer i was on highway and i floored 3rd gear to 9k redline, shifted into 4th floored it again and around 7k rpm engine lost power, cel came on (vtec malfunction), and car was on limp mode. We changed vtec oil pressure switch, changed gaskets and cleaned the solenoid and after...ewerything worked perfectly then to the end of the season. This year after winter, i started the car after 3 months, went for a ride, everything was normal and vtec still worked fine. Few days later i floored 3rd gear, exept this time it was different, the engine did not have any power above 7k, rpms were climbing to slow. I stepped of the gas pedal and tryed again after few kilometres. Again, at 6k vtec engaged and car loss power above 7k and this time cel light came on. Again vtec malfunction.

So far ive done: Changed spark plugs, vtec pressure switch, gaskets cleaned, oil changed, checked al wires.
Now i dont know where to look next.
Ou and when i cleaned vtec solenoid, the filter was not clogged it was clean.
The car has aprox. 150k kilometres and burns about a quart on every 4-5k kilometres.

Thank you for your answers.

i did, Vtec malfunction. I solved the problem vtec solenoid was clogged with small ripped part of gasked cleaned it again and booom.... vtec is working again

I had a leak on upper vtec gasked so i replaced it with homemade gasked an it was too thick, so when i tightened the bolts, gasked got cut on the edges and clogged it.
