Engine Performance problem
1999 GMC Jimmy 6 cyl Four Wheel Drive Automatic 87000 miles
My car makes a pinging noise when you start it like when you put a playing card on a bike to make noise, when you start out the pinging goes faster, however the car wants to stall out along with the ping noise. Once it gets moving the ping noise will eventually go away. My mechanic replaced my fuel line up and back. It stopped for a about 2 months, but now the exact same thing is going on again only this time it will not start. My batter is good I took it to Auto Zone to be tested. I'm not sure what to tell the mechanic.
