Started with a misfire cylinder eight. Changed all spark plugs and coil eight. Ran good two days then misfire cylinder seven changed coil seven. Did not run somewhat better but still misfired but no CEL. Ran two weeks this way. Then yesterday after two weeks CEL back on. now it P0174 Lean bank 2 and also random misfire code and misfire cylinder six after one minute of light on it begins flashing. I have had the truck twelve years never seen it flash so I quit driving it it was was running bad. Any thoughts?
