I have 1994 buick century 83000 miles. When I start the car and when its cold it will idle rough and it wants to turn off. Idles very low and then speeds up and the again untill it worms up a lil bit. And when taking off from a dead stop it jerks it goes slow but once it starts movin over 5-10 mph it will work fine.
i have no idea what it could be

Have you ever tuned it up? Fuel injection service? Is the check engine light on?

Those engines had some injector problems. Try measuring the resistance across them all cold, then warm the engine up and do it again. A fuel pressure bleed down check might not be a bad idea
