How much oil did you put on the filter...

 

None. It came pretty oiled from K&N

What was the code?

Only code it had was miscommunication with ECM. I assume that was caused when i pulled the ECM fuse. Otherwise, no other codes

If the pipe is bigger than the old pipe you have a tune issue. It is not reading the correct air flow.

If you oiled up the filter too much you may have had some coat the MAF and you need to clean it off...

Otherwise you likely have an air leak somewhere in the CAI and it is pulling in unmetered air due to improper installation. If the CAI is made of any material other than Plastic or a Ceramic coated metal you do NOT have a Cold Air Intake but a Hot Air Intake. It will absorb heat from the engine bay when sitting still and this heat will be transferred to the intake air.

I do believe the pipe is bigger. I will measure tomorrow when I get off of work.

That is about how long my only K&N experience lasted.
As time has progressed, so has MAF technology.
That allows more accuracy.That accuracy allows tighter control. That control allows better diagnostics. That means subtle changes in the intake that used to go unnoticed now are detected as faults.

So, would you suggest a tune?

The correct answer to this question is...
Remove the stuff you bought and put the production parts back on.
The ONLY thing you gained by installing the aftermarket parts was the sound.
You lost HP
You lost torque
You lost fuel economy
You lost reliability
And most of all you lost $$$.
2 possibilities as to the problem.

1oor fit and or poor installation has created an air leak between the MAF sensor and the engine.
This allows un-metered air into the engine causing your performance issues and setting all the codes (traction will be disabled with almost any engine code)
2: Poor design of the CAI itself creates turbulence or dead spots in the air flow in the system. Either of those will also allow unmetered air into the engine.

Think about this.
The seller of the kit you bought made all kinds of claims about what it would do.
If changing the intake would do all those things why wouldn't they make the production part that way? Why would GM not give you the extra "free" HP.
The production stuff is plastic because plastic doesn't transfer as much heat as aluminum.
The production stuff if shaped the way is is because they want smooth laminar airflow across the MAF sensor and into the engine.
Simple big round pipes may not do that.

Gotcha. I’m going to call K&N tomorrow to see what they suggest or if I can return it and re-install the stock back on

Because GM is trying to hit CAFE requirements and the owner presumably doesn't care.

You know, it's funny. The first GXP I ever drove had a CAI. No lights, no problems. My mechanic has had one on his Ram for 10 years. No lights, no problems. OTOH, I had a K&N air filter in my first Monte Carlo and took it out after six months.

I believe we've identified the problem, which is three characters which don't appear in your list....

No, a dealer wouldn't change the cal for the CAI.

 

Ya, they said all they could do was set it back to factory.

 

The ECM will adjust to slightly new readings from the MAF if it does change and between it and the O2 sensor will figure out the AFR. As for the MAF being contaminated here is an article from K&N where they have done extensive testing on them:

did you ever find out what the issue was ? I’m looking into buying one for my 08 cts

 

if you are looking for a lifetime filter you might be ok with the K&N but if you are hoping for performance gains you will be disappointed as well as you have a greater chance of doing negative things to your car with that K&N like oil contamination of the MAF sensor...

...if you've read this thread you already know the reasons why you shouldn't do a K&N...

Good luck with your choice

What intrigues me is with the litany of negative outcomes listed from using those type filters (most excellently captured in Post #4), the one issue that customarily misses out on all the airplay is the measured increased quantity of larger micron particulate contamination mandated by the claims of "freer flowing", and as documented by independent testing but curiously unavailable and absent from any aftermarket manufacturer.
Other words, crapfest worse quality filtration. Which is that component's sole purpose in life on any vehicle.
But as is perpetually the most-mentioned yab-but and biggest draw for AF CIAes is, "Yah-but they sound manly", immediately followed by, "They're pretty", and finally, "All the race cars have them".
So, I've grown to let anyone have their run of fun and just transition over to favoring objective data vs. the glam whenever they think fitting. It all goes to that enhanced quality of life thing, which is every driver's priority in personalizing their ride.

All this preaching on just the second Friday of the week.

 

You can buy quite a few superior pleated paper filters for the cost of one aftermarket oiled non-filter.

 

But I want all the free horsepower* the K&N unleashes!




*Offer of free horsepower limited to butt dynos only, and may include extra features such as cylinder wall sandblasting and complimentary mass airflow sensor lubrication.

 

The eternal hope for a free or cheap lunch persists - I have seen some outrageous scams in my 70 years of wrenching on cars and engines, boats and aircraft...... miracle oils, magic additives, and quickie DIY "performance" parts are the most blatant. Unfortunately, car enthusiasts are among the most gullible fish in the pond.
