On my 06 Express 3500
I’ve got codes P2A04 and 300, which is bank 2 sensor 2, and misfires detected. so I’m gonna try throwing a new sensor in.
First off, do you think that’s a good place to start?
Bank 2 Sensor 2 that’s passenger side behind the cat?
Are there four sensors?
Should I do all...
Code PO138/2271 ...so far I've put in new air filter, cleaned MAP sensor, as well as, 2 new sensors; I figured the first one was bad as well. My scan tool states that it is stuck rich and High voltage. Please help
