dead spot in my RPM need help

By jred
- Tue Jun 07, 2011 5:46 pm #258499 this happens frequently to me some times when i start my car "any time of the day"
i get this dead spot when i rev the engine it goes up to 2000 RPM and the rpm drops then then builds back up till 2000 then drops again constantly, and while im driving i lose all power at 2000 - 3000 rpm then the power comes back again and jolts the whole car and it constantly does this until i rev high up to 6000-7000 RPM then it starts to work as normal "sumtimes"

and sometime the car starts fine and drives as normal, im very confused since i know very little bout electrical issues, at least i think its electrical :?

or could it be fuel???
anyone got some tips on what it might be?
thanks in advance..

i changed plugs and wires yesterday to see if that was the problem cause my wires and plugs were pretty old, but im still getting the dead spot :?

but it never hurts to replace the fuel filter.. it's cheap, easy and should be done just about every year anyway

also "it didn't click till now" when i replaced my spark plugs yesterday i noticed oil on the plugs, got a lil back pressure issue with the engine, will that also be a cause for the dead spots on the revs?
