So I installed my AFE Stage 2 Intake and now I have a CEL and it idles a bit rough... sometimes stalls... Any ideas?

I have a AFE stage2 in my car and it runs fine! have you unplug your negative in the car for a short time (10 mins) Maybe it has to relearn since theirs no restriction!

I have the following check engine lights... P0171, P0113, P0111... will try unplugging battery.

Code Reason
PO171 Fuel System Too Lean - Bank 1

PO111 Dirty air filter
Intake air temperature (IAT) sensor harness is open or shorted
Intake air temperature (IAT) sensor electrical circuit poor connection
Faulty intake air temperature sensor

PO113 Same as above

A little Googling goes a long way. Looks like you messed something up when you installed your intake - check for disconnected wires in the area - TMAP sensor is nearby, along with other connections. One of your filters or the plumbing between it and the turbo intake could be clogged.

I've had an AFE Stage 2 intake on my car for nearly 3 years - never a problem.

I know what the codes mean... I can't find what is the cause tho. I didn't discounect anything but the MAS. Also this is N55 not N54!

[chazzz]

MAP sensor is probably covered with oil from the new air filter, causing false reading and throw error codes?

I have a DRY filter!

is ur MAF sensor facing the correct way -
remove MAF sensor and reinstall - sometimes it's not seat'd properly
and will give u an error. The rubber gasket is thick, make sure to press down
firm and it's flush with body. nohomo.

you should be fine.
if u still have a problem put back ur stock intake
and see what happens.

What he said. Double/triple check to make sure everything is plugged back in securely. Make sure any connections are sealed (In the intake tract). If everything is good and nothing is wrong, put your stock intake back on and see if the codes go away.

If anything, go by Camber-Toe to get it checked out. Lynbrook isn't far from Bethpage.

MAF all the way.... Note the arrow of air flow. I've installed mine, removed at dyno's and threw it back multiple times.... Never an issue at all. Check ur plugs and connections!!!!

[FrankiE90]

all i'm gonna add is, nvr had a problem with
my Injen intake....

thought u guys would like to hear that.
...muhhhaaa...


where's the OP.

[IancoleTX]

Bro I almost guarantee you it is the silicone fitting between the upper and lower piping. I had the same problem (not sure on the codes) and I had overtightened that fitting. It needs to connected with a feather touch. Try loosening that fitting all the way, tightening it about 60% as much as you think you should, then clear codes and drive around. If that doesn't do it, move down the list.. but I think that's it.

[JcLusso]

It was the silicone fitting as I figured. I took the intake off and put stock back on and I am returning the aFe. I don't like the build quality for a retail price of $400-500. I rather wait for BMS to finish there prototype intake which is similar and wont have this problem because it uses the original fitting. Very disappointed...
