This morning I had to replace my Crankshaft Sensor
. After replacing the sensor, I drove it for about 2 miles, and while I was stopped at a red light it started idleing rough and wouldn't hardly go. It was almost acting like it wasn't getting any gas. I have not done the switch on and off to get a P code yet just wanted to see what everyone thought it might be. I am hoping that I need to reset my computer because of the new Crankshaft Sensor or is the Throttle Position Sensor??
