Re: egr tube removal?
I have a 98 4-cylinder, and just did the job. I was going to replace my tube, so what I did was to cut the tube just above the nut using a hack saw blade. It cut very easily, as my was rotted. Then I could put a socket over the nut and with a 1 inch socket and a 1/2" drive ratchet, I was able to get it off. You will want to spray the heck out of it with liquid wrench or PB blaster, because they probably haven't moved since the engine was built. And if you buy the wrong tool, just keep your receipt, and they should take it back, no problem.
It's a nasty job, so just be patient.
