Since a battery failure and his replacement, at start in the morning idle is higher (1200 rpm) for a while then go down gradually, and sometimes A/Cis cold at passenger side and hotter driver side with the same T° on dashboard. TB is 2002 model with 28,000 miles. Any idea, advise, thanks to let me know there is no GM dealer where I am leaving but can find computer to check the TB
Cheers
