the connection to the maf sensor on my car is fairly loose. when i touch it, it stumbles and shuts off. would it add too much resistance to the wires if i was to get a new connector and splice into the wiring harness? if not, where could i get a connector?

 

There would be no problem in wiring in a new pig tail . You can get one at a GM dealer or AC-Delco dealer. Some auto parts places might have a generic brand connector you can buy.
