I'm wondering if anyone has dealt with worn or leaky fuel injectors in their yj? I have a new fuel pump and all new sensors and when I'm on the freeway for a while holding the throttle in the sane place when I shift into neutral the rpms dont drop right away. Then may go from 2000 to 1500 then 1200 ect. Also after restarting the engine after 10 to 15 minutes it starts rough then is fine. What do you guys think?
