hey everyone,
I recently replaced a faulty iac valve on my bullit. it ran fine for a couple of weeks. recently it started idling at 900 rpms where before it would idle at around 750 rpms. i took the iac vale back to the dealer and exchanged it. still is idling to high. i also changed the tps sensor and it didnt help. why would it suddenly be idling higher now? any input would be apreciated. thanks everyone.

Do you have a tuner on the car like a Predator that you can monitor your motor? It sounds like you definitely have a vacuum leak somewhere.
