False flow readings from flow sensor.

[dave80]

How can I test my flow sensor for proper operation. I'm getting false flow readings on the gauge with the car idling only and with the gear in neutral. I assume vibrations from the engine is not the problem. I tried rotating the flow sensor in few different positions with no luck. I found this while google searching and will give it a try:

**********IMPORTANT********************

I spent a long time trying to figure out why my flow sensor kept picking up readings when i wasnt spraying! Very annoying! So go to autozone buy some heat wrap
and wrap the flow sensor *thats connected to the FAV* this will stop the false flow. Found out magnetic fields can cause this so save yourself some time....Your Welcome
