When i am driving my car and im in 5th gear if i push the gas pedal almost all the way, my car does not accelerate. When I slowly let off it begins to accelerate but then just drops again until i keep letting off. I dont know what is causing this problem, I just replaced the DISA valve but it did not help the problem. If you guys can please help me out and let me know what is wrong?

does the rpm go up when you push the gas? I'm thinking clutch might be slipping.

no, when I push the gas the rpm and mph drop and for some odd reason when i let off just a tad bit it raises then drops again and it just repeats everytime i let off.
