The problem is that VTEC doesn't start on Prelude '93. Oil level is max. No mods were done to the engine. And rev limiter starts on ~6500rpm. Any ideas guys? No check engine lamp (if i disconnect vtec solenoid the lamp goes on, so the problem is somwehere else i think).

 

is this after teh car has warmed up already?

 

I know,that on cold engine vtec not working

 

cleaned vtec solenoid filters and now at 5000rpm i got a kick again!

 

Now is another problem. Then I start my engine and he warms up, once redline goes to ~8500 and another times ~65000
