Please help!

you could check the injectors to see if they are all firing , they amke a noid light for that ,, one may be stuck open , plugs and wires were replaced ? did you gap the plugs or put them right in , I guess it was running poorly before your tune up ?

Yes plugs, wires replaced and yes it started running really bad to where it dont want to stay running and and when I go to accelerate it bucks and struggles to go and then it diesI'm beyond frustrated

i had a 2005 impala there is a fuel presure censor that is located by the throtle change that out and you should not any more problems mine was doing the same thing once i replaced that it was all good

let us know what happens , if the new pressure sensor did the trick .

Thank u guys soooo much! I will try this and see if it works and I will let u all know
