I am at a loss... I was meticulous in my dismantling and reassembly of my Disco for water pump and gasket repair. Wires were carefully labeled and reattached and everything tightened and cleaned. It started, but immediately the check engine light started flashing at me and it started clunking. Codes for misfire on 5 and 6. I have been through it and cleaned everything that could be cleaned, rechecked wires, and am certain that I have everything in the right order. Heads were not warped and there were no issues with the gasket. Suggestions anyone? I am about tapped out.
