there is a fualt in the electronic engine control system, the on board computer (called a "PCM") has put the car in limp home mode by limiting the electronic throttle control, u need to have the system tested for the fault code that was stored in the computers memory when the the check engine light came on to determine the problem and the course of action to fix it, Kragen and Autozone and other stores do this fault code test for free, but i caution u on accepting advice from the parts techs, it is usualy wrong and it costs you hard earned money to find that out when the problem isn't fixed by there guess, have a factory trained tech look at trhe problem..

It could be a number of things, I would check the EGR valve first as that is quite common on the HDI EGR "exhaust gas recycler" reuses any unburnt fuel in the exahust gas and forces it through the engine to keep your emmissions down and improve economy. often these get mucky so you can remove them and spray them with carb cleaner! do not use anything else to clean them.
To check also any air pipes that have splits. tears, rips etc have a feel around the underside of each air pipe as again this can ause that fault.
Lastly check the air mass sensor going into the air box, I cannot reacll where it is on that model but they are very obvious once your looking at it. normally a wire going into the main air intake of the car, unplug or unscrew it and again clean with carb cleaner and refit.
try these before you pay anyone, lastly it could be an injector leak sucking in air, you can test this if you can get to the injectors, poor a little water around each one and see if they blow out any water or bubble up and **** the water in, this can be a cheap fix but the labour invloved may be expensiove, in all honesty buy a haynes book as its pretty simple just takes a while.
Hope this helps, if you are unsure what I mean then get back to me and I will explain.

tammyspenton, This problem could be caused by a number of things, but the first thing that comes to mind is that you have a TPS (Throttle Position Sensor) or associated wiring problem. Seeing that it does not react when you push the pedal to the floor. You may have a bad sensor that has put your vehicles computer into limp mode and this will have to be replaced before it will operate normaly again. Good luck with this.

i do feel that you will need the exclusive dealer software to locate the problem ,yes i could throw lots of things up that can cause this sort of problem but unless you have a automotive multimeter with scope facilities that you pinch the feed cables and test all the components and the knowledge to do this then you can locate the fault but other than that then you will need the specialist software that only a dealer has ,i would suspect the air flow sensor first but ???? changing parts without knowing the fault could cost a lot of money
