Hey i'm not sure if this is normal or not but my car runs a whole lot smoother when it is cold or when i first start it up. the shifting is freaking smoother and everything is just smoother then when the temp goes up the normal temps, it gets really notchy when shifting. it's also harder to shift into second gear. I just changed my tranny oil about a month ago and it was the same before i changed it. this is my first manual car so i don't know if this is a common thing for manuals..

 

it's physically more difficult to shift gears, or when you do shift it's jerkier?

 

i have the opposite, my car drives much better after it warms up

it could be that when it's colder, your engine stays at higher rpm keeping you from hitting low rpm and stalling. I know in the NorthEast it's cold here and my car is starting at 1500 rpm when i start my car

It seems my car runs alot better when its fully warmed, I notice that my car bogs when its cold

 

fuel atomizes better when its cold, so the car will run better...

 

ive owned 2 5spd honda's and they always seemd to shift better when warm. somtimes if im late for work and i dont have time to let my car warm up for the usual 5 min period, i give it a min and go and it seems to get jerky when i shift gears, till the car warms up.

time for a little break

 

motors love the cold air.

 

Motor loves cold air but runs better when it warms up.

I don't really thing the engine loves cold air, but us the drivers do because that is what yields the most power. Motors are designed to be running at normal operating temp and that's what the internal components/specs were designed for.

hmmm well thats just really weird. i would expect it to run smoother when it's warmer too but it's the opposite for me. oh well

How fresh is your oil and tranny fluid?

 

well i replace both about 2000 miles ago.

 

I noticed my car gets a little grumpy feeling towards my oil change time (3000 mi) but right after I do the oil change it is smoother no matter if it's hot or cold.

is it the engine or the transmission that is "jerky"?

I think what you may be referring to is what nocable4me touched on. when the engine is cold it has a much higher stationary and moving idle, meaning that when you let off the gas to shift the RPMs don't drop nearly as quickly so if you generally shift pretty slowly it would help rev match itself.

Otherwise I can't think of a reason why it would run more smoothly in the cold.

ITS ALL MENTAL... trust me ive thought about soooo much stuff in the past. Now im just like F$%^ IT if the car is running fine than all is well.

 

yeah i shift kinda slow just when i'm driving normaly. well not that slow i guess just regular shifting.

i used honda mtl when i changed out my oil. thinking about using some of that gm syncromesh stuff people are talking about.

 

Um...mines the EXACT opposite. My car runs like sh*t when its cold. Well I guess every car is different.
