O.K. So I had to get a new K20 dropped in because I hydrolocked the last one. The first engine used to hit vtec at 5300 rpms. the new one is supposedly hitting at 6000 but it's not nearly as powerful as it used to be. doesn't even really feel like the cams are opening up. Last weekend I got on it and it threw a CEL. The code was P1259 (vtec malfunction) everything i read said to start with the oil. Did that. Still not hittin like it should. What's the next step?? I need help

take the vtec solenoid off and clean the screen. See what that looks like

i'll try that. thank you. and is there any possibility that it's something with the wiring?? that's another thing i've heard but i'm not sure how to deal with that if it is.
