Hello everyone. I've been trying for months to fix my truck. It has idling problems and when in park or while driving the etc light comes on and I have to pull over and restart it. So far I have cleaned the throttle body and pcv valve. and replaced the iat sensor. I think its a big vacuum leak. As of yesterday I had to get my truck towed because I think the starter died. While under the truck I took some pictures and I want to make sure its not missing any parts or bolts.

This one concerns me the most because it looks like a bolt is missing and oil coming out. Would this cause a big vacuum leak?


The next two just concerned if anything is missing? This is right above the starter.


This is looking through the left front wheel and I see holes straight back.
