Connect a vacuum guage to the intake port and,
look for a cracked or, broken vacuum fitting or, line your engine is occasionally getting too much air this causes it to over rev.

When I accelerate hard to pass my check engine light comes on and the vehicle goes into limp home mode.


Get the vehicle looked at by a garage. The reason it goes into limp home mode is to protect the engine from further damage. The reason the check engine light comes on is because the engine needs checking with some urgency.

Hi ,
You need to have the fault codes read,this will point you in the right direction,the revs die as it is going into limp home mode to protect itself,by turning the ignition off and then on you reset the ecu untill it detects the fault again.

Sluggish acceleration traction light comes on


this must be a 2.3 miller cycle. it is going into "limp home" mode. when this happens, it wont rev over about 3k, and tcs off/tcs lites come on. it feels a lot like fuel cut. probably the check engine lite is also on, and what codes are stored? most common is P1525/26 and 1540, which are the solenoids that control the abv. the abv controls boost, and when this valve is not working proplerly, the pcm stops communication with tcm, and it goes limp home. if you can locate the solenoids, they are on the back of the engine, right next to the egr valve. from right to left, you need to look at the second and forth. you need to ohm them when they are hot. normal is around 26. if they are over 30, or 0, they are bad. there are other possibilities, but this is most common

High revs and surges when driving.


The revving to 2000 then dropping the 1500 likely means that it is in "limp home" mode. When there is a serious problem, the car will put itself in this limited mode to avoid further damage, and to get itself back home without stalling (hence the name). Since it stalls, its likely that there is a serious problem with the fuel system, and the limp home mode will not help you any more since you keep driving it like that. 
As far as the problem goes, it could be just about anything. Almost positive it has to do with the fuel system, but could be so many different things.
Hope this helps!
