PO507 code on 2008 touring roadster
 

Idle error code PO507 , 136K , possible culprit ?

PO507 Light On
 

Tks,
Car is unmolested, but added K&N's to both airboxes 3K ago. Will clean both Map Airs first, then service both throttle bodies , and at last do the idle relearn
fingerscrossed :)

If it's surging a common cause is an air leak in the intake, vacuum hoses or the intake manifold. Make sure everything is snug. I would borrow a vacuum guage from AutoZone, make sure the vacuum is at least 24-25 and steady. If it is, great, move on to the steps you mention. If not, spray brake cleaner until you find the leak. gl.

No surge , Vacuum good , off with the Maps and Throttle Bodies .
Tks Team !!!
