1997 Buick LeSabre Custom 3.8L Misfire
Posted to GM Driveability on 9/1/2006 5 Replies

We have swapped injectors, coils, plugs and wires. Running compression shows around 80 psi on good cylinders, only 50 psi on affected cylinders. I'm leaning towards a cooked engine, but others remain unconvinced. Any ideas would be appreciated.
