My car runs fine but its been garaged for a couple weeks and now it stalls when when I'm driving I thought it may be bad gas so I drove out all the current gas and filled back to the half Mark then put in bottle of gas treatment it helped some put its still stalling while driven and hardly any power when pedal is pressed to the floor but after holding down gas pedal it does gradually speed up so can someone tell me what They think will unclog my problem Also I have replaced wires and sparkplugs and cleaned fuel injection
