Hi, my name is ***** ***** are vacuum controlled, so when you accellerate, you loose vacuum, the system is suppose to hold vacuum with a check valve built into the vacuum resevoir, when the check valve goes bad, this will happen, you can replace the vacuum resevoir, but we just install a one way check valve going into the line at the firewall, and will prevent the vacuum from bleeding off under load, are you planning on fixing this your self?
