Vtec on and off not working properly

**Eze** · 05-05-2010 04:28 PM

Hi all My vtec has been coming on and off lately like itll kick in at 6k rpm then die at 6.5 and come back at 7.5 and random shit like that. Anyone have any suggestions? Ive already checked oil and pressure.

cheers

get a vtec light wired up and check if the signal itself is turning off or not . this should give you a good basis to begin with.

what mods and what ecu are you running. and last mods done to your car would help

Car is quite stock but i just upgraded the exhaust and high flow cat, that cant have anything to do with it

check oil, check speedo sensor, check vtec wire...if still same after those check have been cleared, then run a diagnostics...
