1991 Oldsmobile 98 Regency Elite 3.8L Poor Idle Quality, Hesitation, Surge, Misfire, Poor Fuel Economy
Car started about a week ago just missing under heavy accel. on the highway and now even runs rough. Runs great at idle, but under load seems to break down. Ign. timing seems to retard when accel. under load with brake on. Any ideas.
