I corrected the procedure above to reflect the proper way to do it. Proper means not spending almost the whole next day trying to figure out why your car doesn't run worth a dam. Basically, you should do as 2.5Turbo did - don't remove the stop lever. (I updated the first post to reflect that, so if you follow those instructions, you should be fine)
