    Pulsing problem

    Ok I'm having a strange pulsing problem with my car. It runs fine up to 45 mph from there on up to 70 mph. Under low load like if I am trying to go from 45 to 50 so I increase the gass just alittle. The engine will pulse about 200-300 rpm. The other strange thing is it will happen randomly. One day it will do it others it will not. I recently got a tune up and it stoped for a bit but came back again. So I'm out of idea's its also not throwing on a check engine light which is the hell out of me. Any idea's any one?

    Check the cap and rotor. . . if that isn't it, check out the IAC, all filters, fuel pump (doubt that's it), and make sure no vaccuum lines or anything were unhooked. Does it feel like it's starving for fuel, not getting spark, or not getting enough air? If you need any other help, go ahead and call my cell, it's in my sig. Later.
