My 323 seems a little slow?

I mean its always been quick but now it seems a little slow lately. Not sure what it could be from.

I am trying to think what it could have been, I replaced the vaulecover gasket, and also put in some new NGK spark plugs. Thats about all the stuff I did befor it started seeming a little slower than usual.

I mean it might just be me.

hows the oil looking ??

Looks fine. I just changed it not too long ago.
