My car seems to run very smooth when there is overcast if not raining. Like the low pressure has something to do with it? Is it just me or does it infact have something to do the weather? What is responsible for this and how can i fix it to adapt to the summer months, if not all months...?

I have noticed that it runs better when it is cold outside, but that is just due to air density because of the temperature. Maybe you are experiencing a similar thing it just has to do with humidity and temperature as well.

Bubba, the other issue may be underhood inlet temperature. I know the old red car gets just a bit "soft" after 2 hours on the highway under bright sun inthe heat. I reckon the inlet temperatures are doing it, or mild vapor lock issues. Gotta get a ram air deal going on.
