Periodically, the vehicle will run rough at idle. Turn the car off and restart and runs fine. Most of the time, the vehicle runs fine. Recently, went to obtain an emissions inspection and the test identified the following codes: P0313, P0300, P1085, P1353, P0155, P1345, P1347, P1343, P0171, and P0741. I have had the P0741 check at a transmission shop. They could not identify and issues with the operation of the transmission.
My car has 133400 miles.
My car has an automatic transmission.

Hi there. Most of the codes that are coming on are for a misfire on cylinder number 3. Check the spark plug and wire on cylinder 3 and see if you are getting a good spark. Then check the fuel injector on cylinder 3 to see if its working by unplugging it. If the cylinder changes and makes the engine act up even more, then the fuel injector is working. If there is no change, then either the injector is not firing or the cylinder has a loss of compression in the cylinder. At that point you would want to check for compression on cylinder 3 to determine if it’s a fuel issue or an internal issue.
For the transmission code, the torque converter clutch solenoid has failed in your transmission and needs replaced.
