I havent rechecked my mid. With the hole in the exhaust side of the blocker plate I no longer get the check engine light and got the return of auto stop and the possible cylinder deactivation and ev mode. Yeah, you loose those too.
The Insight pulses the i-VTEC solonoids at idle when warmmed up with no load and under light load to only use a few cylinders. This is when at times at idle the engine sounds more like a singer sewing machine than a 4 banger. Turn on the ac and you got the idle of a 4 banger. The singer sewing machine sond is the pulsing of the solonoids at the rear of the engine head.
