my Toyota celica 96 1.8l EFI surges when reaching 2600 to 3500 rpms. it will clear up after that rpm range and run great up to that rpm range. I have completely replaced Plugs, Wires, cap, rotor, coil, fuel filter, OS sensors, and now dont know where to go from here. I have 180 lbs in each cly. Could the EGR valve be giving me this issue or injectors?

Make sure the fuel pressure is within spec. Also, check the crank sensor.

I have changed the Crank sensor and had the car put on a diagnostic in a shop and they tell me the computer is cuting back the fuel -7% at ideal and -14% when accelorating. also put a new air filter on the car and i know that this doesnt matter much but just want to give all that i have done on the car so far.
