While towing on the highway, the check engine light came on and I lost power. Took it to schucks and the #2 and #3 code misfired. Found plugs burned. Replaced plugs and cop's. Still misfiring, replaced all plugs 37,000 miles ago other plugs look good. Any suggestions?

 

my bro has the same truck and had the same problem i replaced the plugs and the coil on the cyl that misfired and that fixed it, You prob have to change the coils on #2&#3 cyl the coils are about 90 bucks each.

 

thanks for info, unfortunatly replacing plugs and cops did not fix the problem, checked harness back to master plug on passenger side firewall and have continuity, after short run, pulled plugs and they are wet so dont think a fuel issue, mabey a PCM problem?

 

Either that or you have a stuck injector. But you'd think that would show up on the codes.
