It just started to hesitate in the morning only. It seems as I get to work, it is running fine. I noticed that if it is raining, then it really runs bad in the AM. But like I said before, in the afternoon it runs great. Help!

Cap, rotor wires may be the source. I would use a/c delco or delphi parts on this one. You may be able to reproduce the problem in the afternoon by misting water at the distributor, on the wire down to the plugs.

You were right, it was the wires and cap. The wrong spark plugs were put in, which caused the the cap and rotor to burn. Needless to say it is costing $520 to fix. Thank you for your response!

I thought I was trying to help someone. It wouldn't have cost $520 our way.
