i been having a issue lately when the power in the car starts flapping like a power surge...
example1: ur house lights all sudden die and come back up quickly... this is a similar issue happ to my oz and im thinking i have bad plugs and/or wires..
i had a similar issue with my old 2nd gen probegt and my engine died on the tracks but i was able to restart the xar and drive off...

its more noticable when ur at a stop or sitting idle

i just had my 60k service done too less than a month ago

 

check ur battery posts if they are dirty clean them and see what that does

 

ill try that.. tomorrow after work that is if i can pry the - term off that bolt pita to remove
