Failure for someone that is determined is only temporary!!!!! This is just how u learn. Yes it takes way longer than having someone teach you but believe me, in the end you will "get" the leason much better. Be patient and everything will work out. Sounds like you have a small problem so don't freak out. One suggestion, since you didn't remove the distributor, and it ran fine before the tune-up, don't pull the dist. just to see if it is right. It is if it ran good b-4. Like everyone says, you've just got a defective part or MOST LIKELY, just made a small mistake. Besides, you've got a treasure-trove of people here to help you!!! That's more than the average joe has when learning something new!!!
