Hello all,
Long time reader but this is my first time posting. I picked up a new toy this week (91 fj80, 170k original miles, 3FE). It had been idling extremely rough and in order to keep it from stalling you had to give it a little gas... with no OBD 1 codes
First thing was to check all the vacuum hoses and test them, then checked the AFM, then cap, rotor and plugs. That all checked out and I ran a compression test. Well every cylinder was in spec EXCEPT cylinder 2 (counting from the front) which had zero compression. I stuck my finger on there and it almost felt like it was sucking.
Any thoughts? Stuck valve?
Going to try to get the valve cover off today if I get time. Who knows when the last time they were adjusted.
