Poor acceleration

[micarro]

I have a problem wih my car oldsmobile 93
when I start moving it in the morning the acceleration is extremely and anormaly poor I barely can move the car and is consuming more gas than before
After 10 minutes driving my car runs better, I noticed that engine must be warm to fix the problem
Battery is new, I did recently a tune up and the problem remains
I will appreciate your help
Thank you

Does the problem disappear when the engine is warm? Or just get a little better?

Sounds like one of the many sensors is dying. I would start by checking the coolant temperature sensor and the intake air sensor since that makes the most logical sense to me, but it could be one of several sensors. I can't think of anything mechanical that would be causing it. It could be a fuel issue but usually that would create a rather noticable bucking or oscillation in power, not just a steady low power.

Any check engine lights?

Thank you
Well, yes problem disappear when the engine is warm
no engine lights on
If it is fuel issue what kind of issue could be ?
Thank you

Something is obviously wrong with the cold idle/run circuts.

When cold it sounds like its getting to much fuel, or ignition curve is not being advanced enough.

But I know nothing about 93 Oldsmobiles, so I can't tell you why.
