If your in gear (D) for example and you hit the gas, engine revs, but car doesn't speed up, it's a problem with your transmission, and the first thing you can do is have the fluid level checked, and add fluid if needed. If that's not the cure, take it to a transmission shop & have it diagnosed.

Hi there,
This problem is most commonly caused by a weak fuel pump. It will need to be checked with a fuel pressure guage. If you can obtain a fuel pressure guage you will need to observe the fuel pressure while accellerating to see if it drops out.
good luck

dirty or bad idle air control valve i would at worst the egr valve but most likely the idle air control valve which controls the air and idle from the throttle body try taking it out and cleaning the tip as well as in the throttle body where the control valve goes in if that dosent work replace it and the check engine light does not have to be on for it to be bad.good luck to you.
