Code 0703
Hello group,
I need some advice please. Just a couple of weeks ago, I replaced coil packs number 2 and 4 after a month or so of DTCs and driveability problems. Car is running great now, and the gas mileage is back to normal but yesterday I got this code 0703 (Catalyst system fault (left bank)) I assume that left bank is the same as the front of the engine by the grill. At least this is the way I had to order the coils for those two cylinders. After doing a search in the forum, I couldn't come up with a direction to take on this issue. I have no air leaks, misfires, etc. Thank you for any help you can give me.

Hello group. Well, the code 0703 is still coming back after a couple of weeks or so. Other than that, the car runs great. Should I bother with this, or could it cause more serious problems. Thank you for any help you can give me.
