I went out and started the vehicle to go to work and as soon as I put in drive idle started to fault and so I put in park and vehicle idled just fine put in drive and the idle was ok until I pushed the gas and vehicle faltered. I found if I leave in drive and don't push the gas it will drive at idle speed but I push the gas it sputters like its not getting the fuel it needs I have already changed the fuel filter,plugs,and plug wires one at a time so I would not mix up fireing order
