What is Trailer Hitching?
– A contribution by Dr. Keith Delahoussaye that sums up trailer hitching, the problems it can cause and why, and what you can do to solve it. Post Date: Tue, 23 Oct 2001 Subject: Re: Bypass Valve and vacuum leak fixed! List: imon@lists.merkurowners.org >Please define “trailer hitching”! Ever tow a really heavy load on a trailer, and lift the pedal while driving a steady state?? The trailer alternately pushes and pulls back on the hitch, jerking the tow car around. With a loose load, and some wear on the hitch, it can REALLY make things interesting . . . Lifting the throttle on a turbocharged vehicle at decent RPM and boost can create a similar effect. Snapping the throttle shut forms a pressure wave that can rebound off the throttle plate so hard, it will lift it open slightly, relieving the pressure, letting them drop, and so on. Also, that reversion wave smashes in to the impeller wheel, sometimes with enough force to bend the vanes, and has been found to bend the throttle plate. Lon
