Hi guys,
Just want to share with you guys what I did today. I replaced the brake booster vacuum hose in the engine compartment due to codes P1128, P1130. There were two air leaks, one at the intake manifold rubber boots, and the other was the vacuum hose. It took me an hour to wiggle the old one out, and another hour to wiggle the new one in, but it was doable. Here're a few photos, and hope this info would be useful to anyone troubleshooting those codes.
