I own 2 '03 Z's....the yellow one was built near the beginning of 2003.....no problems.
The black '03 Z/Sportsline, was built towards the end of the year and when ever i start
this one in the morning or even if it sits for a few hours, it runs like a bag'o @!#$.
Once i turn it off and start it again, it's all cured and runs like it should.
I've searched this forum for any answers and so far I've only read something about
'03 year end "brains" need to be updated to an '04. Is this true?
I'm not planning on going out and doing that if it isn't gonna make any difference.
Is this common for the '03 year end?
Anyone have the same issue?
