My car is 1976 Chevy Impala.
Recently, a strange thing happened while the engine was idling and my foot on the accelerator pedal and depressed about an inch and without warning the engine began to falter , the ammeter needle dropped almost all the way down, akin to turning off the ignition key for a moment, then turning it back on. Why did that happen, anyway ? Something to do with the carburetor, choke mechanism, or what ? Got me worried and mystified. Any way to find out on this forum.
My mechanic says he's too busy to check for the rest of 2014.
