did u unplug the battery when you installed it? try unplugging it for a while to reset the ecu, then start it up and let it idle for about 10 mins. if that doesnt work, check your sensors and connections.

Did you remember to plug your MAF back in? It's sounds like you forgot to plug it back in.

so i didnt really think this could happen, but it did. my maf sensor is backwards!!! i didnt make anything of it when i installed the intake, but i called k&n, and they said it wasnt normal. they sent me a shitty intake tube. here are the photos, if you guys are confused onto what i mean. they are sending me a whole new intake kit

(hopefully it works after i get this fixed)

Damn! What are the odds of that? I bet the guy that did that weld was hung over as **** for doing it backwards.

thats crappy. after i installed my cai the check engine light went on then off a few times and does for a little every once in a while. it just doesn't understand why the air/fuel mix is different than the last 4 years lol
