[Vwdiesel] glow plug testing/removal

[raymond greeley]

Because of rough running, on less than all four cylinders, at start up, i 
believe several gp's
aren't funtioning as desired. I'll put an ammeter in line to confirm and 
then one by one
test each  with hillbilly testing (cycle twice and finger test temp). When i 
finally narrow it
down, am i going to remove  anything in the way or is a long 13mm box wrench 
the answer,
1/8 turn at a time to get #'s 1 - 3 out. ray
