Blackwing/CEL

I installed a Blackwing on my 05 yesterday, drove maybe 20 miles then CEL came on. I have not checked codes yet as my scanner is at my office. I'm assuming it will be a lean code. All connections are solid, and no cracks. My question is does the car need more driving for PCM to make corrections for more air flow?

I'm guessing your assumption is correct and you'll see P0171 and P0174 codes.

And it is doubtful that more drive time will help from my experience, but maybe Dano will chime in.

Blackwing is a very popular CAI, I can assume that in most cases they should function and not set CEL. One should not have to get a tune with just a CAI and catback.

You would think the LTFTs wouldn't be affected that much, but unfortunately that's just not always the case. A number of CAIs will cause a code to be thrown.

Sounds like you've already double-checked for any potential vacuum leaks, but it might be worth another look.

I scanned today, and it was lean codes. This car has 6k miles like new. It it soo aggravating to install new CAI and get codes.

Sorry, brother. I understand your pain and disappointment. Been there, done that with my C5Z many moons ago.

I have not driven it again yet, but pretty certain I got it fixed. I took it back apart, and it had 2 good dust bunnies attached to the MAF screen. I'm assuming it was from the packaging. So if this fixed it, make sure inside of the duct and filter are debris free...
