i have a bad idle. it starts to jump from 900-2000 every time im at a red light and its not only annoying but a waste of gas. my CEl is also one but its and off and on thing. ive talk to alot of ppl about the problem and even took it to Oz to fix it but it still isnt straight. Alot of ppl told me it could be ether my iacv or my vacuum line i was wondering if anyone would be able to help me or vouch for someone thanks
