Digidog, I am confused. I bought a 05 limited convertible about a month ago and installed a new battery and switched over my key fob(the original had broken at the key chain attachment. I started developing skreem start symptoms intermittently about a week ago so I just popped in a new RCM after reading that RCM might cause intermittent start issues. This did not fix the car. Symtoms are the random 2 start and die, then try to start and nothing. However if I wait about 3 minutes(without disconnecting the battery) she starts right up and typically I can run a few errands starting and stopping without the symptoms. Then randomly like the next morning, same skreem symptoms and, rinse and repeat. So I can drive her but intermittently she goes thru the no start sequence. I read your post regarding voltage potentially causing this not a bad SKREEM. Any ideas? Thanks, VinnytheB5
