Mechanic Job in Clackamas, Oregon

My 2000 Dodge Durango starts but will not stay running unless I keep my foot on the gas. I had a head gasket replaced a few months back and was running well for a bit but began to run rough again and engine light came back on. The heater doesn't work very well, and has over heated once this past summer. The breaks overheated once this past summer as well and after all that the abs and break lights came on.
