Back up and running finally!
Ran into an issue while I was reassembling everything tho. Got the intake on and started plugging stuff back in and found out that when I pulled the intake back off last weekend after finding the coolant leak, the rear passenger side injector broke at the plug. The piece that broke was still in the wiring harness plug! So, until I can get a replacement, I replaced that one injector with one of my original, green 4 hole injectors. Still runs great.
Finished buttoning it up, filled with fresh coolant again. No leaks this time! Took it out for a test drive and filled it up with fresh gas. Runs very smooth now, no more slight stumble at idle when sitting at a stop light. Can't say if it has more low end power or not but it does get up and go a little better than before. Will have to give it a tank or 2 to see if there's a change in gas mileage. Super stoked it's done and running/driving great again!
Engine before I started this little maintenance/mod adventure.
And the finished product.
