My van has been shaking like a washing machine with an uneven load when I hit speeds of 45-55. It stops after I get above 60 or I let off the accelerator. Spark plugs and fuel filter were changed and it helped for only a few days. Now that it is cold it does this worse than ever. The hot and cold climates seem to agitate whatever this problem is.
