My first guess woul dbe the throttle position sensor has gone out, but it could also be the connections are bad from setting... There is a test procedure if you have a V.O.M. - google the test and also EFI management systems. It's amazing what you'll find.

And don't forget to do the same searches within YouTube, a lot of videos on these very topics.
Thank you 34_40 and Joatmon! After running a test on the TPS, mine appears to be good. I wasn't able to find any bad vacuum lines but perhaps I'm overlooking something? Video below:
