94 Nissan Altima 230K miles - Erratic idle in morning

Post by **acuevas123** » Wed Dec 10, 2014 10:57 pm

Hey All,

My Nissan altima has an interesting issue. In the morning when first starting it, the idle is a little erratic after warm up. Then after about 30 mins of driving it seems to 'normalize' itself. However, do get a few misfires throughout the day. Any ideas are most welcomed.

Thanks.

Is the idle slower than normal? Many altimas will idle faster when first started. My car idles around 1100 rpm on cold start, then goes to 500 to 700 when warm. If the idle is much faster than 1000 rpm, it may be a fuel mixture problem. Any EGR codes or check engine light?

Thanks Timothy, figured it out it was a vaccume leak.

I am very happy you were able to fix it. Which hose went bad? In my car it was the the valve on the passenger side of the intake manifold. Where was yours?
