I have a 1991 2.5l diesal prado. I have problems starting on cold mornings. When it does start it smokes for a few mins and runs really rough. In addition I have very little power for a few miles. I have changed the heater plugs and checked that the relay is working properly with a multi meter at the plugs and have run out of ideas. Any suggestions would be really appreciated.
Thanks
