I've got a 95 max and I recently put a new knock sensor on. Now when I start my car in the morning(when the car is really cold), the car turns over but then will die if I don't give it a little gas. And once I get the car running, the idle stays at like 1k even when the engine is really cold, whereas it used to idle a little higher when I first start the car. Does anyone know why this would be happening? Did I torque the bolt on the sensor too lightly? or maybe too much? Any suggestions, thanks.

 

Why don't you just adjust your idle? It's the big black screw on top of your IAC valve. Raise the Idle so you don't have this problem anymore.

 

don't start messing with your idle until you know what the problem is. have you reset you ecm? is it drivable? more details needed.
