High Idle
High Idle
After installing a new cylinder head on my 2003 MCS, my idle refuses to drop below 1000 RPM.
When the car is cold, the RPM at idle fluctuates between 1000 and 1200, dropping to 1000 after the car is warmed up.
I am also getting an SES light with the code that indicates excessive idle (P0507 Idle Control System RPM Higher Than Expected). Other than that, the car runs absolutely amazing.
Any ideas?
