1998 Silverado K1500 5.7 Vortec
I have a 98 Silverado that will stumble while driving at light throttle. It will not do it at heavy throttle or while coasting. I have found several problems, replacing the distributor, wires and plugs. It runs better , but it still stumbles. No codes. No misfires on the scan tool. HELP????
