1999 Buick LeSabre Custom 3.8L Poor Idle Quality, Hesitation, Cuts out, Misfire
Any ideas or help would be great on this one. Vehicle has a poor idle and misfire. No codes and seems to be cyl's 2 and 4. It does have a new lower intake gasket and upper intake but does not seem to change a thing. Plenty of spark, fuel pressure is good, good...
