Hi guys, glad to be here. I have a Dodge Durango 2008 with 5.7 hemi..Two weeks ago I changed all 16 plugs due to multiple misfire code and it has been running great and still does but suddenly I am getting P1128 and PO132 twice on bank one. Any Idea where to start looking first I would appreciate. Runs great just don't trust it for my wife on the road..

 

Likely the P1128 is BECAUSE OF the P0132.... The latter is referring to The O2 sensor, bank one, sensor one, voltage high. If the sensor is original, replace it. That may solve both issues.

It may be original I have 140,000 miles on it. Thank you I will try replaceing the one before the cat. Correct me if I am wrong but bank 1 is the drivers side?

 

Also do I have to use Dodge parts or can I go to Napa...Thank You...
