Allright, i got the feeling my Vtec wont hit in sometimes..
I did a couple of runs gear 1,2,3.. and then brake all to 8900/9000 RPM.
After i noticed/thought my vtec didn't hit in, i removed the plug of the Vtec solonoid (now i dont get vtec, right??) After i did that, i gave speed again and waited to vtec hit in, nothing happend. But it was the same feeling as the 2 runs before... So.. whats broke or soo..?
Also i did not get a Engine code...

low oil pressure = no vtec. how's your oil level/pressure?

How do i mesure? My Oil level is at 3/4th

you'll need to install an oil pressure gauge to monitor pressure. The oil light on the dash doesn't come on until there is little to no pressure.

If the engine is in good shape, maybe it's just an electrical gremlin.

Or the screen on the vtec solenoid gasket could be clogged :thumb:

if the speed sensor isnt working correctly you will also not get vtec.

Vtec only works with you have the correct load and oil pressure.

The engine is in good shape, only 60,xxx KM on it.
idk about the speedo, it looks oke.. when i drive with 80 past a speedtrap, it wont go off. lol

Definately oil pressure..

the VSS will cause to not turn on also..

Also it wont kick in if the vtec solenoid isnt receiving ample voltage
