Hi all,

got a problem on my 2003 Is200 automatic. when it gets up to temp it runs really rough and shows a flashing cel and P0301. this is a misfire on cyl 1. I have replaced the coil pack and all six spark plugs without success. It has also recorded a P0701 ( system too lean on bank 1 )

O2 volts bank 1 sensor 1 = 0.965
O2 volts bank 1 sensor 2 = 0.03v
O2 volts bank 2 sensor 1 = 0.32v

Using android and Torque Pro

there is no visible sign of any wiring damage and i desperately looking on what else it could be. any help would be greatly appreciated

thank in advance

Check for an intake leak.
