counting down isnt going to get you anywhere, just sit tight and if someone can help you they will and please do not double post it is against forum rules.

 

I removed the last 'countdown' post you made since it was of no benefit. As Mike said, please be patient. If nobody replies, then that means they do not have an answer for you. It's unfortunate, but that happens sometimes in a forum for free advice and help. A professional mechanic will be more then happy to diagnose the issue for you right away, but it won't be for free.

 

okay gotcha
