Just installed an Airaid Intake system with the Poweraide Throttle body spacer on my 5.4L and now the Emissions Control Light is coming on (the one that looks like the engine). The light is staying on the entire time. The truck seems to be running great but what could be the problem???

I installed everything by the book all the connections are in place does anyone have any ideas? Does it take a few days for the OBD to recognize new air adjustments?

Also my 1714 Super Tuner is going to be here in a day should I wait to utilize it or just do the flash to the OBD and see if that works? If I do use the 1714 will it save the data with the Check Engine Light on? I dont want to have problems in 2 years when I go to smog the truck at registration renewal time!

Anyone else have this problem?

 

Get that throttle body spacer OFF of there and return it, or sell it, or put it up on a shelf, or use it for a paperweight - that's all it's good for. There are some older GM TBI trucks & then the newer 5.2 & 5.9 Dodges trucks that they can actually do a little good on, because those vehicles use TBI injection which is basically darn near a conventional carb. body with a pair of injectors inside, so the spacer can actually increase plenum volume - which adds a few HP at higher rpms, that's' an old drag racer's trick. But it's not going to help any of these 1997 & up F-150's.

On the 2004 3-valve 5.4 F-150, you also need to be very careful & precise when installing the Airaid intake as well - that gasket that goes on the bottom of the air handling tube right where it connects to the throttle body is easy to not have exactly right on there, and if so, will cause a lean condition. When we install them, we use a second person to help rotate the entire assembly in place, while the other pays close attention to the gasket (well, it's actually a rubber donut, kinda-sorta) as it seats on the throttle body. take some time before actually attaching the Airaid to the throttle body to make sure that rubber seal on the end is *perfect* - the smallest deviation can cause an air leak and a lean condition.

DO NOT continue to drive around like that - you need to use the 1714 to scan for codes to see what the PCM is reporting, as if it's a lean condition that has to be corrected right away on those 2004 3-valve 5.4's - they no longer have a traditional MAF meter.

To properly install that Airaid system takes a good 45-60 minutes for a first-timer, and takes us over 30-45 minutes even with as many as we've done - it's more involved than any previous F-150 intake, so it takes time, and has to be done *very* carefully. Virtually all problems with codes after installing the Airaid on the 3-valve 5.4 are actually installation issues with that gasket/seal not being properly seated on that air handling tube, or the air handling tube not being all the way down to the "ledge" on the throttle body.

Get this fixed BEFORE installing the 1714, OK?

Good luck!
