   Yukon would not idle without turning off on its own. Check engine light came on. Took it to my mechanic. Check engine light was flashing which indicated an active misfire. A running compression test found little to no compression from cylinder 6. Further investigation found that cylinder 5 had been repaired in 2022. Mechanic recommends engine replacement.
