So,
1. Noise from under hood, sound like an electric motor "overrunning" during start up, dies down after a min.
2. The noise stopped 3 days later vehicle stops accelerating around 40 mph and then dies down to 20-30 MPH.
3. Some reserch told me the acceleration issue might be due to Throttle Sensors?
4. Firestone ran a diagnostic and said my SMOG air pump was bad. Part number (33-2504M).

I don't think i need that pump?
Can i by pass it?
Found a few products from Hewitt-tech...but i am unsure of them.

Anyone have any advice??
