My check engine light has came on ran an OBD and it read P0506 Idle control system rpm lower than expected. Any help?

 

She can't breath, - needs an air filter most likley..

 

how many miles? may try cleaning the throttle body first then disconnect the battery for about 30 min to reset the computer\

i found this site you may wanna look at tells you all about that code and how to go about fixin it http://www.obd-codes.com/p0506

 

I have a K&N intake.

 

Thanks for the site good info. I have 75,000 miles. I actually had the battery disconnected for bout 4 hrs after the first time the light came on and I cleared it. Do I have to remove the throttle body to clean it or can it be done by only removing my intake tube?

 

Yea , it's a sure bet that TB is dirty. Your using a junk filter for that truck , that's no way to treat it. Better clean the MAF while your at it, -since you thru a oiled element in the intake = bad move IMO. Run your hand inside the intake, feel all that sand/dirt that gets past that filter? Try it.

 

thats why i went back to a paper motorcraft filter

 

The 04+ with electronic throttles don't like aftermarket intakes unless you get a tune. I'm a bit surprised that you aren't throwing lean codes.

 

mikeyfire08- do you happen to have an edge tuner? for some reason they have been causing the p0506 code with the drive by wire systems.

 

I will take a swipe...thanx

 

No I dont have an edge tuner

 

I took the filter off and the tube was clean I also removed the tube from the tb and that was fairly clean.

 

Disconnect battery/ Clean the MAF sensor -



Reboot PCM.

 

Ok I will give that a try thanx.
