Hi, i found my sassy girl on a farm and not looking so hot.... I won a contest at my job (Dent Wizard) and they made this GREAT running car look new again. But less than a year after having her new dress put on she has been giving me "electrical issues" I have had her in 3 shops for the past 3 mos and NO ONE can fix her. I am about ready to put my second ignition control modulator in and was wanting to know is there anything special i need to do such as disconnect my battery or anything? Please help I would like to keep my diamond but i can't afford more more "issues" any advice would help.
