it may be weak, there is no load. (MOD in path)?

see my text page, on all tests one can do with vacuum path.

The above can be done best, if the stall test passes and the 4 EGR ports are clear.
keep in mind , that 1 port blocked and 3 clear might make the stall seem good, this is why the 4 port car is a pistol to fix/test
