My car runs soooo much better when it's cold

[Mote]

I have noticed this before but this last week was really dramatic. We had a pretty warm summer so far. Last week was high-90's and really humid. Sunday a front came through and BAM - High 70's and no humidity Mon/Tue/Wed.

When it is cool/dry out my car is way more responsive, really gets up and goes from a dead stop. When it is hot/humid it is sluggish, it bogs during acceleration etc. I want that performance all the time. I've never had a car so sensitive to weather conditions.

Is there something I should have checked out? Is it really a Canadian car:-?

Cold air is denser than warm, therefore more fuel, (yes oxygen is fuel) to burn, IE, the cold air intake.

It's that way with all engines, but I've never seen a car that responds to cooler weather more than the MM. 55 degrees is the real tipping point for mine.

Yeah, it's a huge difference. I've never had a vehicle so sensitive. I thought something might be wrong...

Last winter, I was driving my Marauder home in 29 degree F weather....cold and dry.

YEEEHOWWW! It ran like a scalded cat!
Felt like I had a 100 shot of NOS onboard.

Careful though...

Cold temps. = easy tire spin.

Oh yeah!....:burn:

I was testing my 'new found power' mostly on the highway.

[johnnyrauder]

get s/c you'll always have plenty of power..even then you will feel a power change with wether change's but it won't matter....

My car runs great, hot or cold, don't matter. She's a winner!

I heard somewhere it's something like 1 HP per 10 degrees difference. Plus, maybe the aluminum engine is more sensitive to temperature than an iron block.

My Crown Victoria and former Grand Marquis were the same way.

I have a 94 Cougar with the 4.6 with an Allen supercharger and it's crazy faster when it's cold outside. My other Fords don't really care.
