Hi everyone I have a 2007 V6. I see this issue on here a lot but no one ever says how they fixed it. When my engine warms up and kicks the cooling fan on the rpms drop from just over 625 down to 300 and feels like it is going to stall out but never does. I have replaced the battery, fan, relays , throttle body and MAF sensor. Also I load tested alternator and everything checked out. Any help would be much appreciated as I’m getting fed up and tired of wasting money on it. Thanks.
