Hey guys I was driving on the highway back from work today, I go to pass this guy and the second my rpm go up I feel the engine cut the power, I see the check engine light go on and the car won't let my rpm go over 3000.Any idea on what it might be?

Sounds like your car went into "safe mode". There are many different factors which could've caused this. Have you done any mods to your car recently?

Yep, sounds like safe mode. Might be intake related. Did you install one?

check that you didn't pinch the drop in at any point in the box. Your MAF can send your car into safe mode. Check all the components of your intake. Bolts, seals, clamps, hosing, everything. Make sure they are all properly secured.
