I reset the CEL (I have a Durametric)

Today, While driving (Right after changing the oil) the Check Engine light flickered, and the engine felt like it was stuttering a bit. The codes are;

Fault Number:P1130

Does this indicate any issues that changing all 4 O2 sensors wont solve?

Thanks!

I should start with a coil check on cyl. 5 and 6 ( cyl. 5 is located middle left side - cyl. 6 most rear one on the left side ), if they are cracked renew all the coils. Clear the codes and try again.

Any smoke out of the exhaust?
