Hi guys. Got an issue I noticed today which never happened before. So I didn't use the car couple of days. Today I took out the battery and gave it a charge. Started the car and went to the garage. When I stop i notice the dash lights flicker like a Christmas tree.
I started the car and it would Rev and idle if I feed little bit of fuel but soon as I leave it to idle, it would switch off. Drove the car home no problems no dash lights flickering. Once it comes to idle, it doesn't switch off immediately but in like 10 to 15 secs. Is it a battery related issue. I will get the battery tested tomorrow but any help or insight will be highly appreciated.
