Rough Idleing Rio Cinco

My Mom has a 2002 Rio Cinco 4 cyl Auto Trans. It idles at about 750 rpm and is rough and when I turn it up to 1000 rpm it idles good for a while and then dies. Any suggestions ?

Thanks !!!

rios are especially known for chewing up spark plugs in cooler climates. there is a number of updates available for this including the most recent recalls for the reflash and the fuel rail. start with a set of spark plugs and see if it runs any better...then get it to the dealer so they can perform the updates.

smokin: Thanks, there is a recall on the fuel line/rail system and it has been corrected !!!

Thanks, it was due to the recall on the fuel rail which was cracked and leaking fuel.
