pretty simple, vtec used to work good, then one day it doesent.\
b16a into an ef, when vtec hits it hits good for a half a sec, then starts sputtering like its redlining, but only around 45.5k-5k....

Basicly its not engaging fully.

Any ideas...i heard low oil can cause this, but my oil is full...

I added a qt of oil still does it..
Car is fully wamrmed up..
I cleand both solenoid and switch...
It works just cuts in and out.

Sounds like its hitting a rev limter around 5500rpms..
Pissing me off any ideas?

Spark / dizzy A-OK?

I'd check wiring to make sure all that's kosher, sometimes solder can come loose over the years. Good luck in any case.
