Q: No heat when not pushing on gas

asked by on November 30, 2016

My car warms up normally like it should but it barley gets heat or sometimes not at all when I'm pushing on the gas and when I'm stopped it's just blowing cold air I did a heater core flush last year it helped a little bit but still had the same problem if the weather gets a little warmer like 40-50 degrees the heat is hot and doesn't blow cold air as much but when it's really cold it's a struggle

My car has 167000 miles.
My car has an automatic transmission.
