ok well i dont know much about cars and wut not so this might be kinda vague but here it goes

i have a 97 civic coupe with a SOHC vtec swap and my vtec kicks in about 5.6k-5.7k RPM and i redline at about 7k and red limiter at like 7.6 and it has been working fine and everything

but then a couple days ago i started noticing thats its kinda be retarted....my first gear vtec works but at about 6.2k-6-9k my car sounds like it is sputtering or my Vtec is just not working but it goes on and off REALLY fast until i shift...almost like i reached my limiter.......but not everytime...sometimes it works fine

i have NOO idea what could be the problem so any EDUCATED advice might help or if u have questions i will answer them to my best ability! PLEASE HELP ME!!!!! ahhh

 

check oil level. vtec engagement is dependent on oil pressure.

 

check your oil pressure.. you must have 55psi of oil pressure to engage in vtec

 

I'm betting he needs a new oil pan.

Either low on oil or all his "mad vtec popping akshun" caused a dent in his oil pan.

Sounds like he has a heavy foot and his car might be lowered.
