originally i was loosing much coolant and vtec would randomly cutout everyonce and a while.
-i found 2 large leaks once the car was in the air and fixed them(one in a random connector made from the swap and one at the heater core).
-next i did a compression test on each cyl. and it passed with flying colors.
-from there i did a vaccum test and also passed that with great outcomes..
does anyone have any idea what could make vtec not work at times or feel weaker?
