The pop she hears is the accelerator pedal being released and hitting its stop. Had to guess at what may be the problem with out doing some tests, its not a very complicated system, just need a voltmeter, ohm meter and wiring diagram to test 90% of the system. There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subrcription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try http://bit.ly/mitchell_repair_manuals_online
