Default Loss of Power

It seems to me I have a loss of power. When accelerating and when I am at highway speeds 70 + it seems to bog down if I try to punch the gas. I just replaced spark plug wires, pcv valve, and the spark plugs like last fall. Any help would be good thanks

Maybe fuel filter or cat starting to get clogged.

Thefuel filter is pretty new too. I didnt think about the cat though. You think anything else could cause it to do that? Thanks

It's kinda been like that for a while, the new wires and stuff seemed to help plus I just got my tranny and rear end serviced but it just seems like there should be more there. I also checked the egr valve too and it looked good.

Yea I mean it does alot better accelerating now and everything but like at 70 if I push the gas it will go just kinda slow until I really mash the pedal than it will go. Maybe its fine and I am just expecting more. Is there any way I can check on all of it I mean no check engine lights ever come on, should I check the injectors or the coils or will that kick a light on.
