You had a isolated problem.
3800, in my opinion, is one of the best engines ever built.
THat’s what everyone claimed, and no mechanic could diagnose properly a coil pack problem sorry, no longer credible. And I don’t care how reliable an engine is, you match it up with a crap transmission and all the reliability of the engine running means jack.
The 3800 wasn’t the only V6 they used in the LeSabres and Regals.
