P2188 too rich at idle error code
My 2004 S60 T 2.5t is giving me an a P2188 error code. "Too rich at idle" is the meaning of the code. I will start by the usual possible culprits like checking the air filter, look for possible vacuum leak and may be cleaning the MAF sensor and then clear the code and see if it comes back. If anybody has a suggestion it is welcome. The car is driving fine otherwise.
Thanks
Alain
