nearly 2 months ago, i've started to notice that my RPMs are acting weird after starting up the car.
It'll move up and down between 1k and lower. sometimes it gets ALMOST dead on zero but doesnt kill the car...
A friend suggested checking the sparkplugs...

any help?

EDIT: only happens about once a week, if not once every 2 weeks

 

Check your fuel filter, mine did the same thing.

 

Do a search for 'idle' on g2ic.com there's a tonn of info there.
