Add some additive and take apart and clean again. change the fuel filter also cause it sounds like theres something clogging somewhere and it will take some trys to get it all out

1996 buick century misfire

My 96 century with a 3.1 v-6 gave me fits for years shooting a 171 code(running too lean) I wound up changing the fuel filter and the problem went away. If it's been a while since the filter was changed, try it.

My car drives fine but stutters once and a while , but it burns more gas than usual and my engine light is blinking thats why I'm nervous.

a flashing check engine light indicates a misfire that is currently happening. take it to auto zone have them run a diagnostic(its free) on it and see which cylinder is causing the problem.
