Trying to fix my father's truck as he passed last year and it has meaning to me. Getting P0174 and occasionally P0171 but only once every 6 months. Truck runs good until it hits temp and the mix ratio changes from cold pre sets. Once it gets warm enough I get a rattle or knock under acceleration. I've replaced vac lines due to cracking, pcv and o ring, fuel pump due to weak psi, maf, tps, egr, 02.
Last week I replaced the coil pack after 3 and 4 got misfire codes and I did the plugs. All plugs on drivers side the electrodes were rounded while the passenger side plugs were still pointed like new outvof the box, 80K miles on them. My thoughts are that the fuel rail or cross over lines are plugged given the burnt electrodes. From what I'm seeing no one makes the rails so I'm left with a junk yard pull or taking what I have and cutting off the pressed on lines, soaking the rail in carb cleaner to dissolve what I can and poke the rest out.
Can I use high pressure fuel line and hose clamps to replace the old ones? Is there any thing else to look at? Brake cleaner test provided nothing. Swapping out 02 did nothing.
