So I have run into a problem on my car and im a little stumped. My car is still rough idling and giving a drivetrain malfunction even after I have replaced the o2 sensors, spark plugs, and not to mention I replaced the ignition coils about 3k miles ago. It only rough idles when I have started it though and it gets slightly worse for a second if I go in reverse. Though really the roughness gets worse when the actual drivetrain malfunction message appears. So if yall have any tips on what it might be that would be much appreciated.
