My 96 Tahoe 5.7L started missing so i had it put on computer and it showed #2 miss fire so i changed plugs, wires, distributor and rotor. After about an hour of driving it started missing again checked it and #2 miss fire code came up again, replaced plug and ran seafoam through system didnt help it keeps fouling #2 plug. When you pull the plug it is black like it is getting very hot. Checked fuel pressure it is running 55 and holds pressure when you turn key off, checked compression and it is running around 155, went ahead and changed fuel filter. I am at a loss!! any ideas?
