Gas & Sensor 2 2003 Trailblazer
 

My husband just passed away and I hope you can help me. When I put gas in I have to put it in very slowly as the pump keep shutting off (constantly). Service engine light always on and I was told that it has a sensor 2 issue. When exelerating it makes a tiny high pitch squeel until I back off the pedal. Feels a little bogged down when this issue happens. For example 70mph speed limit going up a hill it will do that when the car is trying to meet the speed. Or if I have to for some reason hurry or take off quickly it will squeel. I have never had a ticket in my life so honestly I am not an impatient driver. Thank you so very much.
