it seems like everyone elses car love the cold and mine hates it. misfires every morning on warm up. and the rest of the day is fine. once ambient temps are above 65 my car kicks ass. is this a plug problem? I have bkr6e's for cold weather.

my car loves the cold, eventhough i am in limp mode, i can notice a lil` diference in power. i just moved to tampa and its colder than miami, and i love it so far.

mine likes it once its warmed up, until then though it can be rough... that is to be expected with any car in the cold...

Warm up is always rough for me. But once it's warmed up it loves the cold air.

everyone is just chipped though. My car ran great in the winter when i was just chipped. This pc-16 file just doesn't like dealing with the cold.

PC-16 sucks in the cold especially if you have a FMIC. I remeber everyone telling me too that PC-16 is horrible in the cold. My car runs like shit

thats still not a solution, a solution would be getting the pc-16 file to work in the cold, thats just abonding the pc-16 all together.

is your MPG shitty like mine too? I get about 17 all city and 20 on the highway when the temps are close to freezing. The other day when it was 70 degrees I got 25-26 mpg on the highway.

Let it warm up. Both my 1.8t and the S4 are pretty rough when cold. They are still smooth when kept out of boost but pulling out in front of someone is a big problem.

i'm not feeling your pain....car has been doing great since i fixed the whole damn thing. only stock thing left is my O2 senor and stock cat. everything else has been swapped out...excluding internals. so i think my car is now in tip top shape....i wouldn't mind doing some O2 sensors in the summer...or just wideband and replace the other one.

how does you car run in the freezing cold? What have you replaced? My maf, o2 sensors, plugs, air filter are all pretty new.

well in chicago we have been blessed this year...its not freezing yet but its coming...its been a low of 20...car runs great...very responsive.

i guess the question really is what hasn't been replace....so thats internals, O2 sensor & cat and coil packs are still original.

I bought a new MAF, new plugs, air filter, fuel filter, every seal has been replaced. hoses, vac hoses, fluids, control arms, coolant sensors, oil temp sensor, new radiator, new everything, repositioned fmic a lil lower.

on occassion...my rpms will dip in the beginning when i first fire it up in the cold and its not quiet up to temp...but it goes away...car has always had that problem since i've been on this file. but my rpms used to move a lil at idle...thats stopped or at least a 95% improvement. grant it was only going from like 850 to 900...but it was still moving. not anymore.

O2 sensor and CPs are the only thing that prolly need an update left on the car.

My car runs like crap when cold too. It's a pc-16 thing... after it warms up it's fine, but when it's cold you must stay out of boost otherwise it will start bucking and misfiring very badly...
