So i got a Dejon INtake, I put it on to see how it sounded, and watch my short trim(interceptor) shoot thru the roof. I took it off today to put my factory air box and k and n back in. I got it in and started it up and the car was kinda or sputtering i took it around the block and it stopped, but now my short trim at idle is like 29, I was better off with the dejon on.

any ideas? think it may be the maf?

 

reset the battery see if that helps, i dont have a ss/tc so i dont have fuel trim problems haha! only issue with me is that I take about a dozen seconds longer in the 1/4 mile haha

It does that on all (trim), it is not a properly tuned intake, nor are most all others.

Battery reset will allow you to run the stock intake, but dont put that intake system back on.

K&N is the only good proven one... Take it off, get a K&N, and your problem will be resolved.
