Do you mean you have long cranking times and a rough idle for the first 1/2 block down the road? That would be a failed fuel line pressure check valve located on the fuel pump in the gas tank. Turn the key to ON so the fuel pump runs, turn the key to OFF, now turn the key all the way to start. It should start in 3 - 8 seconds. My 2000 has done this for the last 2 years. My 1997 fires up instantly.
