How long did it take you to get the injectors out?

Took it in to the dealer and they saw code 31. Diagnosis is replace with a new MAF sensor at $1004. Then step 2 is recheck system and see if problem still exists. I assume the next step is to replace the idle speed control valve at $600. The car has gradually gone down in idle over the last...
