Hey guys,

During the recent cold snap last week, I went to start my car on a ~34F day, and it barely started after about 5-10 seconds of struggling. The engine generally starts very easily on warm days, and in past winters, it needed to get into single-digit temperatures for the car to not want to start.

Also, the car has had an interesting cold-engine driving issue for quite some time now. The issue is that the car will accelerate relatively slowly, but if I push the gas down a bit to coax a bit more acceleration (far from WOT), it will often get a sudden kick of acceleration. Generally, these effects are subtle, especially since I drive pretty slowly when the engine is cold; I try to avoid the kick outright, letting the car warm up completely before asking for any unusual amount of power. On Friday, the acceleration was abysmal for the throttle's position, and the car ran rough under any acceleration until the kick (which was abnormally large) came. Once the car warmed up, it ran as though nothing was wrong.

Just hoping somebody has an idea or two for me; sorry if this is a common question, but I didn't see this addressed in the first few pages of the search results. I didn't spend terribly long on it, though, if I'm honest.
 
Look at the time stamps, this thread is over a year old.

As others were saying they were experiencing stuttering while accelerating , luv2rallye posted the results that worked for him. Clogged or dirty injectors would cause a problem , like sputtering because there isn't as much fuel being put into the combustion chamber , or it's not being injected as a "mist" like it should be.
 
Has your motor ever been rebuilt. It can be linked to the injectors or it can be linked to worn piston rings allows incorrect compression until the heat up expand and close the gap in the cylinder. However there is a multitude of possibilites. only real method is trial and error idle screw first then injectors and internal motor absolutely last
