Motor Problems?!?!

[2003eclipse]

Car is 03 eclipse 2.4 No mods 115k miles on it.


Its getting more and more common now, but the problem with my car is I will be accelerating and my motor does not want to rev over 4k while in gear with the gas pedal to the floor it just falls on its face like hitting the rev limiter almost. Did I spin a bearing??? Fuel not keeping up (clogged injectors weak fuel pump) I finally have money in the bank and The damn car just starts taking a shit. Its the feeling of when your clutch slips/ or hitting the rev limiter.
