#137904, "RE: buzzing noise from ecu" In response to In response to 1
When you first start it up the idle is fine but once it warms up The idle bounces between 700 to 800 rpm. Sometimes it will just shut off when you push the clutch and the car slows down. It starts back up but you have to keep pushing the gas. After you get going for a while it stays running but still bounces in between 700 to 800 rpms. Could the IAC be going out?
