Hi having problems with above vehicle, this has had this fault for some time, but we have just done head gasket, water pump, thermostat, oil and filter ie the works. Looked at archieves number 772 and this has same faults,after 5 minutes and hot MIL light comes on with code 505 and revs are at 1025 to 1125. We have checked wiring, cleaned out throttle body and ERG valve and put a known good ISC valve this made no difference any thoughts or FIXES????
