    The van began to idel rough and stalled sometimes, but ran smooth once moving. The Service Engine Light turned on, and I had it checked for problem codes. The code was P0327 and I was told that it could be related to the Knock Sensor. Should I be focusing on a different area?

    it is likely the code for the sensor is a result of the rough running not the cause of the condition, a kock sensor will not cause a rough running engine, all it does is ****** the ignition timing if it senses pre-igntion due to poor fuel quality or a heavy load condition and hot engine temps, Is the engine still running rough?

It is a 2 wire seneor under the throttle body. You will have to remove the air breather and it will be a brass/black plastic sensor. A 3/4 socket will fit it.Good Luck

Just had new brake line , brake pads, rotors installed on my 99 chevy venture van, after coming out of the shop the abs light is staying on, why? thanks


Because you now have an ASB System Malfunction

Most common cause is a Wheel Speed Sensor

Now--was it damaged by the repair shop

or did they not bleed the system correctly

or not clear the ABS Light?
