05 grand prix starting problem

Sometimes when my car start it goes dead, then on the second start it may or may not go dead, sometimes i have to give it a little gas to keep it from dying, then it is good.

It does it no matter how the weather is, but mostly when wet or cold, but not ONLY when it is wet or cold. I have tried different types of gas from different places still the result is the same. I have gotten a tune up.

what could be the problem?

Try cleaning the throttle body if not already done. I have seen dirty throttle bodies causing similar problems on many of these vehicles (04 and newer).

by goes dead you mean car dies? Or do all the lights dim and car stalls becuase of a battery voltage problem?

yes, the car dies instantly, when it does it does it about twice, or maybe more if i don't give it a little gas.

Could also be the fuel filter. Have the fuel pressure checked too.

I cleaned the throttle body, problem is gone! Thanks
