Hey guys I'm new on here and have recently purchased a honda that isn't fully complete and doesnt run 100% befor I got the car it had had a engine swap it now has a b16a. One of the problems I'm having is that anytime I cut my headlights on or hit my brakes or cut my heat on my car dies when idling It has a brand new alternator and battery and doesnt have any vacuum leaks. Any idea on what could cause that to happen
