Okay guys, good news. The problem was that the wire harness to the coil pack wasn't firmly seated on the front coil, where the broken connector is. I placed it firmly on the spades and now the car is running much better. It idles properly now, and for the first time since I've met my wife, the car actually drives well at low speeds. However, I'm now painfully aware of the need to replace the engine mounts, as it's vibrating severely. Anyone have an idea of how bad they are to swap out?
I've got a flashing CEL like I did before under heavy load, but the car accelerates much better now. I'm pretty positive that the catalytic converter is still a problem, but I will have to wait until Saturday to put it on a diagnostic scanner.
But before I can do that, I need to get the fuel leak located and dismissed. Wife was stranded the other day, and it can't happen again.
Also, I hear a pinging sound coming from the top end. It sounds like an exhaust leak, but I'd like your opinions as well. So I'm going to upload a video as soon as photobucket allows me to share it.
Thanks for the help, guys!
