missing under load
I have a 1999 Yukon 5.7 that has a missing problem. From 1st to 2nd, 2nd to 3rd , it startes missing when it shifts into 4th. It really misses bad in overdrive when under acceleration. It also, misses at idle when in gear. I have replaced the distributor, wires, plugs, and cap and button. The plugs on driver side foul quickly, while the passenger side is burning good, no deposits. I need help.
