17915 - Idle Control Sys: Lower Regulation Limit Reached
Has anyone ever had this code?
Mine threw this code twice in past few days (had it thrown two years ago too). Now my car is idling very low and actually stalled. Any thoughts?

Basically, I had a gunked up Idle Air Control and a cracked hose. After I cleaned off the IAC and replaced the hose the problem went away.
The IAC is easy to clean, loosen the three nuts and the IAC comes straight off. Hit it with some brake cleaner and make sure the slide works properly. Clear the codes and see if the problem persists.

Re: I had that problem.
