I reinstalled the upper intake plenum (had to remove it to replace the engine harness).

I re-attached all the vacuum lines and replaced any that were broken (including the stupid $30 PVC line) and started the truck up. It started right up, idled really high, then started to be alittle erratic around 1k RPMS.

I noticed when it was running that fuel was POURING out of the vacuum line that goes to the power steering ACV. Here's a picture of the line in question below:



I hooked up all my hoses according to pictures I took before I removed the plenum and the diagram below.

I looked over the lines again and realized I had mixed up the fuel return line with the power steering air valve line...whoops. Switched them back and it's idling and running great!

I found this cool diagram online and thought I would post it here. Can't get any easier than this.
