My 99 Silverado w/5.3 in it had recently developed a stumble at low revs but goes away as the rpms increase and according to a mechanic friend of mine,who has the same truck,it is most likely a bad plug wire.I trust this guys opinion very much and have been pricing plug wires for my ride which vary greatly according to what brand you want to buy.I do know which wires I need,the 10.5" ones,and the best quality ones I can find locally are Bosch but don't have any experience with them.Are they any good?I'd like to put OEM back on but without ordering them I can't readily get a set and my only other option is Standard but I don't have much faith in them,past experience.
