Have been driving my stang 2013 V6 for almost 2 years now. Right from the day 1 I have noticed that outside temperature somehow made my cars acceleration/ pickup however you call it become sluggish. I feel my car is more monster at night than at day I can easily get to 80 in no time and there have been times i felt uncontrolled power thrown back at me. Am I over thinking or is it really that hottter climate affects engine speed and pickup somehow?? I was talking to a friend of mine and he said it would make more sense if it was other way around since engine gets heated quicker during day( not sure if this really is connected to the pickup part) Is there something I can add up or install to fix this , I top up the fluids every 3 months promptly.
