It all started when I decided to pressure wash the engine bay to get rid off all the old dirt and oil spots.
Took it to the shop and they clear all the countless codes.
After that the check engine light came on days later.
Based on that I decided to get a wifi code reader and to download the DashCommand app.
3 codes keep coming back and you can definitely feel the truck running rough when the light comes on.
So before buying parts blindly, I much rather ask for wisdom.....
Pics and codes coming soon

 

Torque is another good app for reading codes and looking at live OBDII data.

 

here are the codes!!!!

 

Hey get something that puts off smoke or vapor, or spray brake cleaner around hoses and connections to check for vacuum leaks around the engine. A hose and/or hoses may have come loose/cracked/broke. Hook up your reader and check the values switching between the O2 sensors, clean the MAF sensor.

 

1590 can be wheel speed sensors. If you've pressure washed them, maybe the plugs need undoing, spraying with wd40 and putting back together.

The others I believe can be due to leaks. Look up smoke testing.
