Need Help with P0172 code new CAI

Maybe run the engine without the filter element to see what happens? P0172 is an indication of running rich. Something seems to be blocking airflow.

So basically you saying the powercore filter is restricting airflow?

^^^^ I think you have that backwards. @godfather. It could be making the computer dump to much fuel with increased airflow.

I'm suggesting that the quantity of air getting to the engine is incorrect for the amount of fuel, causing a "rich" condition. I know nothing about a Powercore filter. You were the one, in your OP that said: "I just read that the Powercore filter might be the culprit to my issues." Removing the filter and driving the truck, would be an easy way to confirm, or eliminate the filter as a cause. If you did not have this problem, prior to installing the CAI, common sense indicates that something relative to the installation is causing the DTC to set. Or it is just a coincidence. Something is restricting the airflow. If you don't suspect the CAI installation, reinstall the OEM intake and see if the DTC goes away.

If the airflow was restricted the engine would use less fuel and be in a lean condition and that's not the po172 code. With the intake your getting more air and the o2 sensor is reporting to much unburnt fuel (rich). See about getting a street tune and the intake will work fine.

Guys that's awesome. I will try the "without filter method" and see. I'll update with results after my trip from NYC to MD without a filter. LoL

Might as well take all the screens off the windows and doors at your house and leave it wide open while your gone along with not running the filter.:lmaop:

I'm crediting the OP with the intelligence to realize that I was only suggesting he remove the filter long enough to check the results.

See post #7 @ cart. Lol

@cart7881 I know what you was referring to. Let the joksters be. Bwahahaha

Figured you guys were joking but people drive around.without air cleaners on their cars. Not good at all but still. :th_ontopic: What all you done to remedy this godfather? Take your hand and cover up the opening in the intake tube and see if it chokes down or even stalls.Put the stock intake back on it and see if the cel goes out if your going to be driving much.

I've ran a k&n and volant intake on my truck. Even ran the k&n without a filter cause it fell off the intake. It's never cause me to get a cel. Did you clean the maf while it was out?

I believe that was mentioned in the OP, however, it could be defective. The reason that I suggested the filter, at all, was because he said something about reading that it might be the "the culprit to my issues". It seems like a good idea to at least address that possibility first.

Yesterday morning I got up and cleaned MAF sensor. Reset the CEL and it came back after a small ride around town. Today I reset the CEL before heading back home and no cel yet, I still have 3 hrs of travel time.

Make sure the MAF sensor is seated well and that the gasket is good, and that all other joints are tight and leak free. If all that checks out verify you got the correct volant intake for your engine. 07+ with the change to the 3.7L and 2.9L had a change in the MAF tube.

Well the CEL came back while on the road heading home yesterday. Fukker is sucking up some serious gas as well. Yeah the Volant set is correct to my i5 engine. The previous order was not and I sent it back. The filter to the tube is sealed tight, the tube to the TB is sealed tight. However the box hole where the tube and filter meet there is no tight seal. I'll recheck the MAF sensor O-ring and seating for a good seal. At this point I'm just scratching my head, WTF :ugh:

BUMP for any other suggestions?

@ supermodulator would a tune correct this issue? I'm all over the place with this BS.

I just love how so many threads start asking the same question with no resolution update posts. FML

Do you still have the OEM intake? If so, you could put the configuration back to where it was before you got the DTC. If you still have the DTC that will eliminate the CAI as the problem. Although a defective MAF sensor should set a separate DTC, it could be causing a P0172.

Garry - Put the stock air intake back on and bring your CAI with you to the BWW meet and the Cap Chap and I will fix you problem.
