About 2000 miles ago I replaced the wires, plugs, cap and rotor on my 98 Z71 5.0. Used Borg Warner cap and rotor, name brand parts. A thousand miles or so later the engine develops a back fire through the TB and a miss. Probably the cap or rotor, replaced them both (parts store warranteed them no problem), and truck ran great again. Now 6 months and another thousand miles, same miss and backfire. Returned cap and rotor, once again warrantied. The counterman (that I've known forever and is a wealth of info) said this was a common issue and recommended I switch to Delco. Traded for the AC/Delco cap and rotor and truck is running great again. Anyone else had issues with caps and rotors on these engines?
