This happens when the pressures (and temps) inside that cylinder reach a point where the mixture explodes on its own. Since it is pressure dependent, if it happens on decel, it would happen even more on access, when the throttle valve is open and more air/fuel is being let into the cylinder. > I had a wheel off on that side recently. I'll check the lugs.

Another thing to check would be the CV joints. Grab each axle shaft in turn and yank it back and forth axially a few times. They should each travel about an inch. If one of them feels odd, you may be approaching a failure of one of these. I've had CV problems which were "fixed" by just jerking them around like this; I assume this redistributes the grease. - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org
