RevDano Posted June 26, 2017 Report Share Posted June 26, 2017 Hello Everyone, This is my first post other than saying hello in the new member forum, so be gentle! I have searched for an answer to my question in past posts, but had no luck. I put a new CAI on my 2003 SS. For now, because I have so many other things to take care of, I used the generic eBay CAI and a universal K&N filter. My truck runs great and sounds great, but the engine light is on. I pulled the AirFlow whatever-it-is off of the stock airbox and installed in with the new set up. Is that a necessity? Should I have used it? Is it normal for the light to come on? Enquiring minds want to know! Thanks for your help, Dan Quote Link to comment Share on other sites More sharing options...
someotherguy Posted June 26, 2017 Report Share Posted June 26, 2017 You're gonna need to know the code; you can go down to most auto parts stores and they will read it for free. Write the exact code # down and post back. Are you 100% sure you reconnected everything before starting it up? Richard Quote Link to comment Share on other sites More sharing options...
EXGM Posted June 26, 2017 Report Share Posted June 26, 2017 I would check all you connection and make sure you don't have a leak on your "custom" intake.... if you don't have a nice tight fit you could be getting additional air by the MAF and tripping a code. As stated above find out the code and post.... Quote Link to comment Share on other sites More sharing options...
RevDano Posted June 26, 2017 Author Report Share Posted June 26, 2017 Thanks guys, I'll double check all of my connections and if I still have light I'll have someone check the code and post back. Matt, it seems like you're really impressed with my "custom" intake! Quote Link to comment Share on other sites More sharing options...
EXGM Posted June 27, 2017 Report Share Posted June 27, 2017 Nah just giving you a hard time.... I've seen way to many problems with K&Ns..... I made a lot of money when I worked at the dealer for a few years. Loved it when people over oiled their filter and toasted a MAF or transmission......

Enquiring minds want to know! Thanks for your help, Dan Are you able to post a few pictures, and possibly find out what the exact codes are with a scan tool. Glad to help, just need a bit more info.

RevDano Posted July 5, 2017 Author Report Share Posted July 5, 2017 Before I got to someone with a scanner, I rechecked all of my plumbing and shortly thereafter my light went off. It didn't seem like there were any leaks, but no light, so maybe there was. Quote Link to comment Share on other sites More sharing options...
