put a intake on my truck and the check engine light came on what should i do to fix this problem

 

You could start by letting us know what truck you put it on. Then what intake. Then what other mods you have done. Hard to say with no info.

 

Sorry about that, i have 2005 f150 5.4 liters and the intake is a spectra and the only mods i have on the truck is the intake and a cherry bomb exhaust.

 

you are most likely leaning out your truck you need to get a custom tune specialy in that year truck. and what size tube are you running with that intake cos i believe there are two sizes you can get from spectra and the bigger one is not good for theese trucks!

 

i am running a 4 inch tube with the spectra.
