Hi every body, my engin have a hard start because a low votage bettery.
After it start, the idel rev is not stable, it run between 1000rev and 2200rev itself. I have try to switch off and then start again. The symthom not change.
Thank you for you attention

 

but having low voltage wouldn't cause idel surge. check for a vacuum leak, low coolant/air in the cooling system, iacv could be bad. check those and let me know.
