Checked your intake?
Also check flux capacitor mounts and headlight fluid level.

are you running aftermarket ecu?
check vtec solenoid?
oil levels low?

Call Duncan Nissan man, they're experts when it comes to vtec related issues, some say they're vtec diagnosing gods aye

hmm now Im thinking maybe exhaust leak
blocked cat or cracked welds somewhere...
get under there and visually inspect the flanges,weld joins etc. for any carbon soot buildup from leak
