need help. can anyone post pictures of the vacuum line setup? i THINK i have a leak somewhere. also whenever i accelerate i hear almost like a bogging noise. truck tops out around 3-3.5k rpm and tops out around 60-75mph. just changed the fuel filter due to the bad jerking, and it did somewhat solve that issue but it still does jerk.
My truck would do the the same thing my timing was fully retarded distributor bolt got loose and readjusted it self
If you suspect a vacuum leak, turn in your truck and spray break cleaner around all the lines. When you hear a change in the idle there's your leak, but it sounds more like the distributor issue.
