jeez man no wonder your 4runner feels sluggish, thats some serious compression loss. id check your valve seats and your valves to see if any of them are burnt. your piston rings could also be fried as well so yeah it may be time for a rebuild. if you have the tools you could do it yourself, rebuilding engines can be a good time.
