Before the engine work, car had VTEC and no bogging just the idle going up and down by about 200 rpms.
Afterwards (got back from Honda), car does hit VTEC at 5500rpms, and car stumbles and bogs from 2000-3000rpms. Once 3000rpms hit car accelerates fine.
The tech said the he had to adjust the timing because of the IACV is sticking, so now the car idles at 1200-1400rpms when warm. When AC is on idle is around 900-1000rpms.
What's going on? Is it the timing that is preventing VTEC switchover? And what could be causing my bogging between 2000-3000rpms?
woah there, the IACV was sticking so he adjusted the timing? calling that a half-assed attempt would be too kind. clean your IACV and reset your timing. your timing is probably retarded, like the guy who worked on it.

no but f-ed up timing will
