Welcome to the AVEO forum/club! Smart people know Aveos are reliable, handle well and cheap to operate, making the Aveo a great buy for the money. Sorry to hear your Aveo is temporarily not feeling well. I don't know much about what makes Aveos run, but please be patient. There are many members on this forum that are very well versed in maintenance and repair/troubleshooting. I am sure, once they read your post, you will get some xlnt info. It might expedite the reply, if you give the year and mileage of your manual transmission Aveo. Good luck! Keep us informed of your progress and again...welcome aboard! Edit...for what it is worth, your problem and what you have done sounds like a bad ground, but I'm not sure where to look or how to test for one.
