I finally have engine codes. They are P0171 and P0174. Bank 1 and 2 are running lean?? So whats this mean and how do I fix it?

 

Sounds like a Vacuum leak, thats the codes that you get from the classic rotted out PCV elbow..

On the passengers side valve cover find the PCV valve and with the engine running trace the tube back to the rear of the throttle body, checking for leaks as you go.

On the back side of the throttle body there is a rubber elbow that is prone to rot out causing a huge leak. You will feel it with your fingers if this is the case.

Hope this is it... Its a cheap fix.

Also check all other vacuum lines, especially behind the battery.

 

Found no leaks. This all happened after i got stuck in fender heigth mud if that helps

 

Check and make sure you didnt damage the vacuum canisters that are behind the fender liner on the passengers side. I have read about them getting cracked during fender benders.

Might want to look into cleaning the MAF wires incase you sucked up a little bit of dirty water. You can search on MAF to find procedures..

Might want to post a thread over in the engine section for other suggestions.

Good luck
