D16Z6 VTEC problem.
After rev in to VTEC and drop to idle revs, engine working unstable.
We use chipped ecu to do tests. Change VTEC points and no mater how high or low by rews. Engine working unstable after and only when hit the VTEC range.
Disconnect the switch [lug engine rew without VTEC at high rews and no problem with idling.
We change the entire solenoid and problem dose not solved. Still exist.
Problems started after Zex cam install. I was not who install it, the costumer arrives to me with this problem after installation.
