Default Something is wrong

This weekend, I replaced my methanol pump on my car, because the old one had locked up. After that, I started my car, it is was running very rough. It sounds like it is skipping. It won't idle smooth; sounds like a have a big cam in it, but it is stock. I checked my codes and there are none.

Now, while I was replacing the pump, I had to stretch the power wire about 6". I was pulling on it quite a bit. This cable is routed behind the block and goes in behind the battery. The pump is in the driver's side front fender. Anyway, I was wondering if maybe I knocked a wire off a sensor, or something, that would cause it to run so bad.

All suggestions are welcome!

The cam position sensor, MAP sensor (on the intake) and oil pressure sensor are all in that area. The vacuum hose for the HVAC system connects to the intake manifold just below the MAP, you could have also knocked that off. There is only one way to find out, pull the intake manifold .

Would any of these cause my symptoms?

Ugh! Sounds like a project for next Saturday! Thanks for the ideas, all others are welcome.
