when vtec engages it makes a weird hissing noise sound like its air leak or something? really annoying checked all vac hoses etc still nothing. can sorta still feel it but doesnt have that grunt!
car still drives normal though. anyone got any ideas? thanks!
Checked your intake?
Also check flux capacitor mounts and headlight fluid level.
are you running aftermarket ecu?
check vtec solenoid?
oil levels low?
any loose wire?
Intake noise
Looks like missing wires?
yea should got more wires
any clicking noise?
Sounds like you've got a gremlin somewhere

running neptune ecu connected laptop to it no codes, oil levels good, itr intake arm with poddy with lid on or off still can hear the hissing noise at vtec.
nah no clicking noise jst sssssss at vtec pretty anoyying happened out of nowhere when i hit vtec yo!
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

hoisted the car yesterday blocked exhaust no signs of leaks but saw a little tiny black mark at the flange of headers might just be leaking through vtec will try unbolt and reseal ! was just seeing if anyone has had any of these issues before.
lol well ive had the intake on ever since i got my car i would be able to notice the difference, took a mate of mine for a spin and he notices it now aswell and says wth is that!
sometimes they can leak when the engine is tilting on the mounts under loadQuote:
