Check engine light issue

lilchild87 · Sep 26, 2007

I installed my cai 2 weeks ago and everything was ok, now the check light is on for some reason. I checked the oil, coolant and they seems alright, also the idles and drives good with the cai. The small lost power i noticed when i just got the cai between 2,000-3,500 rpms i think it's gone now.

Wondering if the light it's on cuz of the CAI...

any ideas?

P0171 is my guess from your cosmo cai being 2.5"

I think that's the problem. When I did my Header back exhaust with 2.25 piping, I had to change out the Cat. After that the the CEL went away.

I have the OBX-R Headers from Ebay (2.25"), I fabed the midpipe with a Magnaflow high flow cat, with a 2.25" flex pipe and piping to connect the header to the cat back exhaust and I have Bosal Catback exhaust from Protegegarage.com and that's 2.25"

The sound is good until you hit about 3000rpms then it sounds really loud. I am getting CAI so I hope that would change the sound for the better.

I was going to for the 350z sound but that didn't happen. LOL After about 3000 RPMs it sounds really ricey.

which is definatly what I wasnt' going for. I am thinking about getting another Axel back exhaust to change the sound but I don't know.
