its getting really annoying because when i get on it to pass people and it does that its embarrassing. people are saying fuel pump but it starts just fine and you can here it turn on as well

SikSSS no not yet and its been doing this for about 300+ miles. Im waiting for my uncle to bring his tuner program up so we can watch the levels of everything. and to sinr98 ill try sometime thanks weekend. thanks

Hey im guys im new to this site and not sure where this should go so i apologize. anyways i have a 99 gmc sierra 1500 with the 4.8. Just recently it has started to back fire during hard acceleration. and sometimes spits and spudders during take off. what could be the problem? i have a hand held programmer with a cia and exhaust on my truck. it originally did something like this when my maf sensor shit the bed. could it have done so already? i changed the fuel filter thinking that was the problem but no luck. thanks again Brett
