If your car is in limp mode, it would almost certainly be throwing a code with the check engine light on. You've hooked up an OBD reader (or gone to an auto parts store) and had them scan the ECU for stored codes?

I have taken the car to three mechanic all said it was different thing one said it one the VTEC solenoid so I replace it other said it the fuel pump I replaced it as well and the other said it my intake but that makes no sense
