Check Engine Light

<TABLE><TBODY><TR><TD vAlign=top width="100%">I have a 2002 Lightning that has the check engine light on because of the air raid intake i have in it. I took it to the dealer and they said the light is going off because the engine is running to lean. Could this be bad on the engine if i leave it? I also have flowmaster exhaust on it and i dont know if that could be setting the light off also. Any help on this would be nice, thanks.

P1229 Supercharger Intercooler Pump Not Working (Ford)
P0171 System too Lean (Bank 1)
P0174 System too Lean (Bank 2)

I would start by looking at the intercooler pump.

Check and recheck all your vacuum lines to make sure they are in good shape and are still properly connected.

Is your MAF housing seated and sealed properly on the Air Raid housing?

If, when you check your IC pump you find it isn't working, take it out and clean it. A lot of guys have had good luck by cleaning the gunk from the pump.
