1996 Oldsmobile Aurora Question: CAR KNOCKS AND CUTS OUT IN DRIVE,BUT NOT IN PARK

CODES:PO441,PO325,PO139,P1139,P1140,PO300. I'VE REPLACED KNOCK SENSOR, AND REAR O2 SENSOR AND STILL CHUGS/KNOCKS IN DRIVE -
Answer 1
you need to start with the po300 code which is random misfires then attack one code at a time. i rec you see a mech that can give you a good diag and est on these repairs -
Answer 2
Torque converter lock-up solenoid or command bad? Does it feel as if it's a manual trans being put into fifth gear when put into drive? Maybe as said before , you should have TRANS. scanned for diagnosis NOT just codes. Pop-Tarts aren't just for breakfast. -
