CEL on

Car sat all winter while I put DCAI, modified manifolds, and ECU retune on it, now after 2 days the CEL came on, read P5050, Air Idle Control System. I reseated the gas cap, erased the code and seemed good for 4 days, then CEL came on again, same code. Any body have any helpful info? The car seems to run fine otherwise.

P0505: idle control system malfunction? - MBWorld.org Forums

Yeah, that sounds like very good advice. Just love this forum, it really helped to pass the idle hours over the winter, now it's time to drive the car.
