fix to bogging down???

[scort2498]

so recently i would turn the engine over and start driving no problem until i hit the 2500-3000 rpm range... it felt as if it were boggin down when i hit the gas.(only when the engine is cold) so im all like wtf mate.and im tring to determine if it is a fuel issue or air issue(vacuum leak) well i started something new... I wait for the fuel pump to charge all the way and then I start it and voila no more bogging down... does this make sense??? or am i just getting lucky.

mabye your fuel pump? or dirt in the fuel somewhere? idk. thats what im goin to guess.

There is no connection by 'charging' or 'priming' the fuel pump.
It is where it will get in a few seconds anyway.
If this problem is only when cold, you may have a coolant sensor that is reading faulty.
It IS possible that the pump is getting weak. A new fuel filter is a good idea at this point.
And of course, our engines don't like any vacuum or intake leaks.
