Service Engine soon light

[RCChopper]

So i am stationed over here in England and I have an 04 GT. About a month or so now I put on the Accufab Plenum/TB and a Cold Air Intake. Everything seems fine except for when I come to a stop the idle sits at like 1100 for about 20 secs then drops to normal. Then about a thousand miles later my service engline light came on right after i crossed 7200 miles. Any help would be great.

you are probably running lean, but you need to get the code pulled. if theres nothing on base, take it to a ford dealer and they will be able to pull it. if they say they cant, tell them to just hook up the WDS and pull it with that.

What do i have to do to get it adjusted?

 

[bdcardinal]

first you need to get the code pulled. when you get the code pulled, post it up on here and we can help you out with what to do. also, when you installed the TB/plenum and CAI, are you sure you reconnected everything?

yeah everything was reconnected first thing i checked when the light came on. I reset the battery and no light for now but i am gonna give it a few hundred miles. to see if it comes back on
