That's right! When I hit vtec at 5500, I get a check engine and no more vtec. I do not get a check engine light unless I hit vtec. After I turn the car off, the check engine light goes away and there is no code in the computer!"Son of a Bitch" Tell me what you think even if it hurts! Thanks.

 

have you tried to check the code yet. if i'm not mistaken, if you jump the connector, you should still get a code. My guess is it's probably one of the vtec codes?!?

 

There is no code after I turn the car off! I dont know if you can check it when its running.

 

knock sensor?

 

have you checked your oil level?? had this happen to me in my gsr once.. turns out i was just low on oil. changed the oil and replaced the oil pan gasket and all was well.

If it was a knock sensor, the check engine light and code would stay on the computer until it was cleared.

 

do you have an oil pressure gauge? if so what psi are you hitting when vtec engages?


there is also a screen behind the vtec solenoid that can become clogged.

Sounds like you are having VSS issues. once that signal is broken, at wot, a code pops up and bye bye vtec.

You can just check the code immediately after this happens. Next time it happens, just pull over as soon as you can and jump the connector.

You ran out of Vtec. You need to refuel.

2.) what year

3.) what engine

4.) what OBD

...Code 21
He has tried a new vtec unit also.

hey Chris i was thinking...
Im a dumbass first of all ...VSS... lol.

I think this might be my fault. know anyone you can swap computers with, to rule out the possibility that its my ecu that's jacking up. i don't really think so, but its possibly. it does say chiped on the front of it. lol ...Justin.

need to check wiring. im thinkin that the solenoid is not getting signal.
