I did finally get them out. It took a some effort, but now it is done. I did put 5 new bosh glow plugs. The ones that were in the car were probably those problematic Autolite plugs. I did not get a glow plug reamer this time so the carbon deposits are probably still there. I have to take them out once I get a hold of a reamer. Car starts the first time around, but the glow plug light is there intermittently. I have to do some more research around that. Thanks to all for your help.
