Over the last month and the half I have been chasing this hanging idle issue. I have replaced several items like the iac valve, tps sensor, maf sensor and pcv valve but I still have this issue.

If I'm coming to a stop light or sign and put it in neutral, it'll hang around 1500 rpm for awhile then drop to around 1000rpm. Will also do if I just rev it up.

Has anyone else had this problem?
