Do you have an aftermarket bov? If so than check to see if it is vented, if it is than you need to recirculate it.

His car is N/T. Does the car sputter when at idle? Does it rev up past 1000rpm and fall below? LMK

Have your codes check to make sure all the electrical stuff is copacetic. After that checks out move on to other areas.

Your ISC is bad. Test it with a multimeter to make sure.
