Default Loss of power

I have a 98 SLE and I'm losing power some where. I have changed the plugs and wires. I also changed the fuel filter,air filter and pcv valve. Is it time to have my injectors cleaned or do I have another problem? Loss of power is never good.

Can you describe the loss of power more? Does it seem like the car is sluggish? Does it show the symptoms on start-up and go away? Does it happen only at WOT? We need more details

It'* mainly at take off. Once it is going it'* fine. There is no problem on the interstate or even in town. The rpm shoots up at take off, even if you're not giving it a lot of gas. I had to replace the intake manifold. Since then it has been acting up.

Almost sounds like a vacuum leak to me.

Strangly enough it seems to have fixed itself. Could have possibly just been adjusting to the new parts?
