Re: Unstable rpm idle same issue unsolve

Maybe a vacuum leak from intake manifold or somewhere else. Does your car is loosing power?
It's worst if your turn on A/C or release engine clutch a little bit when you're on 1st gear?

Does it run fine on 1st gear or it makes an abnormal engine noise when you accelerate?
Do you have visible fume at exhaust?

A Windstar without having the check engine light is not a real Windstar.
