HEY Guys
My disco is overheating with codes P1300 p3003 p3005. Sounds like my left rear CAT is clogged since the truck is choking at idle. I've read in a few places where a clogged Cat can lead to this type of overheating. So far I've replaced the coolant bottle and cap, the thermostat, the radiator and flushe dthe system. I've checked the plugs and bled the system. The truck still overheats after 5-10 minutes. :banghead:Any suggestions would be appreciated.Thanks
