Have a loose wire on plug going into MAF. Plastic housing on plug is broken, won't clip into MAF anymore. Repair shop has tried to fix but too loose and loses connection once you start driving. Have tried dealership and they are no help. All places say there is no part number for this particular wiring/plug that comes from engine. Trying to find in salvage yard, so far no luck. Any suggestions? Any other model that will interchange this particular piece?
