hello everyone. I own a 1992 isuzu trooper 2.8 tdi with
an 4jb1 engine. i don't know why but my mechanic has switched accidentally or not some of my vaccum hoses and now my car is very sluggish all the time but even more when i go up hills and won't rev up or speed up. does anyone have the vaccum lines diagram, i couldn't find it anywhere? thanks.
