Injector squealing??

[Daeldalus]

a week or so ago when i started my car it sounded like a belt was squealing but would go away after 30seconds or so of driving.... only happens on a cold start...... i figured not a big deal... just buy a new belt and be done. but i checked yesterday to see which belt it was and it sounded like it was coming from the top engine..... i got out my listening device and found out it was coming from one of my injectors. WTF?? i have never heard of this

also about the same time my mpg dropped about 4-5mpg but i can find no evidence of the car running rich( no black smoke and i checked all my sparkplugs)

should i just chalk it up to old injectors and replace them with a cleaned set?
or could i find out if it just one and replace that one?

Wacko.

If you have C191 under the intake manifold, I'd look at that first...

There's not much in the injector itself that can squeal, short of maybe a loose connection.

Unplug the electrical connector from the injector and start your car when cold. If it still does it then it's not the inejctor.

If you have a belt squeeling you should be able to tell by looking at the belt itself.
