Hey Maximas.

It may sound really weird, but I have noticed that my car feels much havier when it is gloomy outside. It feels like I am using 87 and haven't done my tune up. But when it is sunny outside it runs awesome again.

Same thing I've noticed after the car wash. It runs sluggish for about 5-6 hours and then it feels fine again.

Any ideas? Can it be an athmospheric pressure? Maybe humid air?

I would love to hear more supporting statement.

 

It could probably be both the pressure and the humidity.
It could also just be like that saying, "My car drives better when it is clean." ha ha ha

 

wierd

 

yeah humidity changes the air mixture, more difficult to burn oxygen i imagine
