Driving along this week and notice the engine shaking a bit more than usual, finally the check engine light started flashing when i was pulling into the driveway. OBD II gave me 6 codes - P0138 P01138 P0300 P1313 B30FB P12B0

Those last 2 codes I've never heard of before.

On a side note i was getting a P0420 code about 2 months ago. Sensors all changed with new Bosch 6 months ago.

Does anybody have any advice on how to approach this issue?

Thanks for your time, nick
