P2099 and P0174 fault codes

Post by Russell » Thu Jul 26, 2018 4:30 pm

Hey,

I have a 3.8 jk. And have received the fault codes - see attached.

I've changed the O2 sensor pre and post cat on bank 1, and have recently stripped and cleaned the intake manifold.

Using the superchips, I brought the ECU back to stock settings with the same result...

Any other suggestions on what I should look at to sort this out??

systemso lean means the compression of air and fuel have less air it happened before with me and since i cleaned the air filter and MAF Sensor the error did not show for more than 5000 km driving just make sure while cleaning to disconnect battery Terminal

Hey Khaledibd

I just got back from mussaffah now after having the sensor cleaned... as I pulled in my driveway the engine light came back.

Will replace the sensor and see if that's the problem.

Holding thumbs!
