    please post up the actual code that you have


    yes a code can cause the car to go into limp mode (not rev above 3000)

    as for reasons... heres a few:

    timing could be off... timing belt could have jumped
    Cylinder position sensor (CYP) or the wiring to it could have gone bad
    Crankshaft position sensor (CKP) or the wiring to it could have gone bad
    distributor itself could have gone bad
    the ECU could have gone bad


    for starters though, please post up the actual code you are getting along with what you are reading it with

    it is likely a bad sensor... but before shelling out $200ish you might want to trouble shoot it a little before hand

    you said you just got this car, has it always ran this way since you got it?
    have you recently done anything like timing belt / water pump / crank pulley / etc?
    is the CKP plugged in? is the wiring damaged?

    do you have a Helms manual? there should be a test procedure for the CKP in there letting you know the specific ohm readings and such
