1979 Cadillac Elorado 350 motor

Having problem with mechanics trying to solve the rough 30-35 mph
motor running after 20 min, Highway speed okay. Plugs, distb cap rotor and fuel filter replaced. External pump lots of pressure. The Midas shop says the Vin say it has a variable V8-6-4 motor. I said its
a 350 Olds motor. 1981 was the only year of the 368 motor with V8-6-4 system. The ECU has been replaced a while back. Also the
fast idle is way to fast during warm up. Any ideas appreciated.
