I live in los angeles and it gets 120+ deg in the summer is there anyway to fix that? When i accelerate the cold air gets kinda warm and it doesn't get cold until i get up to speed.
Hey Matt15, I just bought my 07 F150 and so far so good. My friend is a Ford mechanic and states that the one flaw on this truck is the fuel filter (if you could call it a flaw). Make sure to change out the fuel filter at 15K miles. This could make the idle rougher than normal. Poor quality gas can also clog up the filter earlier than 15K.
